Power of Trust



"Rozalin: ...Y-you... You are really going to trust me? I am the daughter of Overlord Zenon. I am a demon, and you intend to kill my father. What part of that equation gives you the notion that you can trust me!? Are you mocking me?

Adell: No, no. I'm not. It's just that...I promised myself that I would trust you. And you know how I am with promises..."

- Disgaea 2 Cursed Memories

Trust is a rare commodity. And we mean the premium stuff, not the dime a dozen trust the Horrible Judge of Character dishes out. When someone is trusted by another person, it feels good and may even strengthen the one trusted, like benefiting from a small scale Combined Energy Attack or Heroic Resolve. Those so trusted will feel obligated to live up to that trust, giving the proverbial extra 10%, or sticking with the truster through hell or high water.

When the Power Of Trust is directed at a morally neutral or gray-black character, it makes them feel good in an uncomfortable way... the kind that makes them have to suppress the urge to Pet the Dog. This is one of the things that can make bad guys like The Mole switch sides. (Sometimes they will backslide. However, telling them Remember That You Trust Me can neutralize that effect.)

In the right setting it can act as strongly as the Power of Love or Friendship. Of course, in darker and more cynical series, the Love Martyr and Horrible Judge of Character will think this is enough to change someone and be proven wrong painfully. In certain settings, insulting the one who instills The Power of Trust in front of the trustee can be a Berserk Button.

Because Children Are Innocent, they can wield this without even noticing it. Kill Me Now or Forever Stay Your Hand runs on this.

It's not without its advantage for the trusting character, who can frequently carry off great deeds because of relying on the character he trusts. Back-to-Back Badasses, for instance, is feasible only for characters willing to trust each other, since it gives the other character a prime chance to stab you In the Back -- but if you are willing to trust, the other character may keep you from being stabbed In the Back.

Even if In the End You Are on Your Own, the Power Of Trust an ally bestows can be just as good as their physical presence.

See also Undying Loyalty which can be an end result of this. When trust runs deep, you'll have friends for life.

Anime and Manga
"Ed: The colonel might be a bastard, but he's trustworthy."
 * It's worth noting that in Digimon Adventure, Jou's crest was actually called Faithfulness or Sincerity (the dub changed it to Reliability, which seems to make more sense).
 * Mimi was given the Crest of Sincerity in the dub.
 * Kamina in Tengen Toppa Gurren Lagann is the sort of person who inspires this in everyone he meets, whether they like it or not.
 * Simon too, later on. Part of the symbolism is that the entire brigade supports him and backs him up, and in turn relies on him to win the day. Just as a drill takes most of its power out of it's weight and the force behind it, but still relies on the tip to actually pierce the target.
 * Kanokon provides our protagonists with an All Your Colors Combined sort of super mode that requires an open heart to work. In other words, trust. We learn this after that trust is lost, naturally.
 * In Fullmetal Alchemist, though Ed rarely holds back in showing how much he hates Mustang, he seems to trust him almost implicitly, due to the fact that Mustang's been keeping his and Al's secret for four years. He evens comments in one episode of Brotherhood:


 * Baccano has this involving the immortal 10 year old, Czeslaw Meyer. No, he's not the sweet kid who makes the huge cast of assorted criminals find themselves. After a couple hundred years of bad experiences, he has issues trusting anything in this world. The anime and novels has Issac, Mirria, Ennis, Maiza and Elmer to drive the point to him. It only takes about 70 years.
 * In Scrapped Princess, Shannon has trouble tapping into his hidden D-Knight abilities because he doesn't trust Zefiris enough to use them. When they first try combining, his power gives out after several minutes of fighting.
 * He had his reasons not to trust her.
 * In the Violinist of Hameln the 'Trust' between Hamel and Flute is exactly what stops him from  Also, Trust is what gives Flute the power to
 * In Naruto, the title character was shunned from birth by everyone in the village with the exception of Iruka-sensei. If Naruto didn't have Iruka's trust, things may have been a lot worse. (just look at what happened to Gaara)
 * Also Chouji. Constantly teased for his weight, but reveals during a major fight that if you insult Shikamaru (the one who actually believed in him), he will kick your ass.
 * In Full Metal Panic, pretty much all the moments where Sousuke starts falling for Kaname is when she tells him she trusts him completely. No, he doesn't react very well romantically when she tries to seduce him in skimpy outfits, but boy does his heart start beating fast when she appeals to his trust issues. Justified in that it's shown that all his life, he was never really able to trust anyone like that... so it definitely moves him when she's able to believe and trust in him like that.
 * To go further on Sousuke's trust issues, it's pretty much said outright that his lack of the Power of Trust is the main reason why he has problems using the Arbalest's Lambda Driver. Because he passively hates the machine and is unwilling to trust it, it can't always function right.
 * Hiei of Yu Yu Hakusho sheds his initial tendencies toward world-conquering and the accumulation of zombie mind slaves for no apparent reason other than 'dumbass got lucky and now I'm on parole,' but his Heel Face Turn is confirmed at the 'Gate of Betrayal' in their first team story when Yusuke, with manly beaming smile of trust, nominates him to dart over and pull the lever to save them all, while the rest of them split his load of the crushing weight, and after some debate he actually does it.
 * Somewhat ridiculous in that Yusuke asked him because he was fastest, and if we factor in his hesitation time actually anybody else would have been faster. That he was shortest and therefore couldn't actually be helping them hold it up anyway would have made more sense, but been a lot less cool.
 * He was probably the only one fast enough not to get killed by the huge rock they drop on you in punishment for keeping faith with your comrades, so that worked out okay.
 * What may be odder is the Heel Face Turn-inducing trusting smile coming from a cynical fourteen-year-old who has never had any friends ever except this one girl he played with as a little kid because he's a jerk and bad with people and doesn't like people anyway. Dying is good for the soul.
 * Hiei's initial psychosis was probably the magic sword messing with his head, anyway.
 * Comically invoked in Hentai OVA Bondage Queen Kate with the straight-faced line "If you can't trust your rapist, who can you trust''"
 * A big part of the meister/weapon teams in Soul Eater. More so than strength, arguably more than courage, it's mutual trust that counts; its indicated that without it the teams could not function. e.g Black Star and Tsubaki working out how to use the demon blade mode, Maka and Soul when fighting the Clown and later Giriko.
 * Trust between partners is also a major theme in Tiger and Bunny. Throughout the entire series, the eponymous characters, forced to become partners in episode 2, must learn to trust each other, both personally and professionally. Indeed, explicit and implicit lack of trust for each other causes the most rifts in their friendship; conversely, expressed trust in the other helps them grow as people and partners.
 * In the first arc of Higurashi no Naku Koro ni,
 * Trust in his teammates (instead of viewing them as a collection of physical attributes to be exploited at gunpoint) is part of Hiruma's Character Development in Eyeshield 21.
 * In the, Sena realizes that Hiruma was trusting in him to   past the point where it would still be statistically possible for their team to win. It spurs Sena on to do just that.
 * In the same game, Hiruma throws a blind pass as he's being sacked, even though holding onto the ball would have been the safer option. Based on the opposition's defensive formation, he just knows that Yukimitsu will be exactly where he needs to be to receive that pass. Touchdown.

Comics Books

 * Inverted in Mighty Avengers. Evil god Chthon, who gets more powerful the more people believe in his existence (which he enforces via terror), finds out that there's even stronger source of power for him - the lack of trust for a man who was trying to stop him, Henry Pym.

Fan Fiction

 * In Kyon: Big Damn Hero, this was what motivated
 * Pretty much the second-half (so far) Story Arc of Misfiled Dreams.

 * A major theme with Pony POV Series. Twilight even points out that trust is instrumental for friendship to exist.

Film
"Sean: Trust: is a very important thing. *Tosses apple to student who's slouching in his seat* Jeremy- you want to tell us why this is?
 * Horribly subverted in Reservoir Dogs. feels obligated to confess to, who has taken the bullet for him, that he was the rat all along. The latter then tearfully, but promptly, executes him.
 * In Good Will Hunting, psychology professor Sean Maguire is lecturing his class:

Student: Because trust... trust is... life.

Sean: Mm, well, that's- very deep, thank you, Jeremy."


 * In Aladdin, just before leaping out of the window of a high building, Aladdin offers Jasmine his hand and asks: "do you trust me?" Later he asks the same thing when inviting her for a carpet ride, which gives away his disguise.
 * Jasmine's answer both times is: "yes", the first time uncertainly, the second time with a smile.
 * Her initial response, a surprised "what?", is also the same both times, the first time more panicked while the second is more confused before she figures it out and smiles knowingly.
 * In National Treasure, Ben has to save both Abigail and the Declaration of Independence. He asks if she trusts him; she says yes. He promptly drops her in order to save the priceless document. He apologizes afterwards, but she simply assures him she would have done exactly the same thing.
 * This is one of the core tenets of Cars 2.

Literature
"The depths of trust and the honour Garro had done him was immeasurable."
 * The core premise and a prime Aesop of Les Misérables is founded on the concept.
 * In Sandy Mitchell's Ciaphas Cain novel Death or Glory, Cain catches their guide Sandy Kolfax drinking. Cain demands he hand over the booze; then he hands it back and tells Kolfax to bring it to their medical man for use as supplies, to undermine his resentment.
 * In Sandy Mitchell's Warhammer 40000 novel Scourge the Heretic, when Elyra and Kyrlock are undercover, Elyra lays out a plan to Kyrlock that involves their splitting up, Kyrlock is uneasy: he could easily escape both his home planet and the Inquisition entirely, but Elyra would be entrusting him with her life, and he's not sure he could do it. Then, when a man goes to rape a girl in front of them and offers to share with Elyra to appease her, Kyrlock says he will take him up on it and gets close enough to brain him; Elyra shoots him. Afterwards, when Kyrlock says that he knew she would back him up, Elyra is embarrassed to realize how nearly she didn't.
 * In Ben Counter's Warhammer 40000 Horus Heresy novel Galaxy In Flames, after Garro, on Tarvitz's bare word, shoots down Tarvitz's pursuers because Tarvitz is his friend and battle brother.

"If you doubt and hesitate, we are lost! Why should I bring you up out of the pits to betray you now?"
 * Later, Horus persuades Fulgrim that he trusts him because he gave him a sword whose powers they both know, which nearly killed Horus himself.
 * In Graham McNeill's Warhammer 40000 Ultramarines novel The Killing Ground, Uriel is subjected to three ordeals to prove that he is untainted by Chaos. The second involves pulling a sacred relic from boiling oil. When he says before that he will succeed, Leodegarius, administering it, says he hopes he will, with obvious sincerity; when he is struggling with the pain, Leodegarius looks at him with obvious desire to have the evidence to prove his innocence. This confidence is what gives him the strength to do it.
 * In Snow Crash, Uncle Enzo takes some enemy agents prisoner. He spares their lives in return for their service. He then deliberately leaves them unguarded, knowing that the trust he's showing them will be more binding than anything material. He's right... not that it matters in the end.
 * Not long before realizing that Good Feels Good, Lara Notsil of the X Wing Series, sitting in her new X-wing in flight, sees that Wedge Antilles, Ace Pilot and hero of the Rebellion, is flying ahead of her, no shields. She could get a shot off, kill him easily, then jump into hyperspace before the squadron responds and get covered with glory by the Empire. But although the thought occurs to her, she's not even really tempted. He thinks she's a regular recruit, and he trusts her, and she justifies inaction by thinking she'll wait to betray the whole squadron, but she's Becoming the Mask.
 * In Simon Spurrier's Warhammer 40000 Night Lords novel Lord of the Night, Sahaal reverses the process: when he confides even a fraction of the truth to a woman he is deceiving, it feels good.
 * In the Harry Potter books it is a major plot point whether Dumbledore's trust of Snape is correct or if he is a Horrible Judge of Character. Dumbledore many times asks Harry to trust him. Let's just say there is a lot of trusting going on, much of it rather reluctantly.
 * Dumbledore wants to trust everyone. Half the time it works, too.
 * In John C. Wright's Orphans of Chaos, Amelia recounts a fantasic story and all the other children immediately vote that they are in a crisis and must take all precautions. She is moved by their trust.
 * This trope is how Cordelia Vorkosigan gets "results beyond hope".
 * In Robert E. Howard's The Hour of The Dragon, Zenobia implores Conan the Barbarian to trust her, and he grudgingly does.


 * In "The Shadow Kingdom", Kull is given a stolen gem to inspire trust, because he can now betray the man.
 * This is one of the central themes of Worlds of Deep Space 9: Cardassia in the Star Trek Deep Space Nine relaunch. Vedek Yevir appeals to the virtue of trust in order to prevent a 14-year-old would-be suicide bomber from going through with the attack.
 * In L. Jagi Lamplighter's Prospero Regained, Astreus mocks Miranda for declaring she would never trust him, telling her to trust no one and they could write on her tombstone "She trusted no one."
 * This is a rising theme in the Mistborn trilogy, and one of the keys to victory in the last book.

Live Action TV
""Now you got all this education, and made me look the fool without tryin', but I still got a gun to your head. That's 'cause I got people. People that trust one another, that do for each other and ain't always lookin' for the advantage.""
 * Doctor Who: almost every Doctor, at one point, said, "Trust me, I'm the Doctor," or variations.
 * This goes both ways with his companions, and can make for some Crowning Moments of Heartwarming. The "I believe in her" speech from The Satan Pit is a great example of this.
 * Battlestar Galactica: both ways between Adama and Athena
 * In an episode of Doctors a terminally ill woman and her son successfully use this on the woman's homeless brother to persuade him to look after the boy when she dies.
 * The Power of Trust is a major theme of The Sarah Connor Chronicles, where John Connor absolutely trusts Cameron to protect him, even after she goes haywire following damage to her chip and tries to kill him, and then suffers temporary amnesia.
 * Firefly: River's trust actually managed to make Simon a Determinator . For some time he was the last person left that she could trust. And the knowledge of that fact probably pushed him on.
 * Mal also discusses this at the end of "Our Mrs. Reynolds," when he catches up to Saffron.


 * This theme almost becomes Hatter's Arc Words on Alice 2009. On first meeting her: "I see. You don't trust me." Midway through the mini-series: "You still don't trust me?" On saving her life multiple times, getting tortured, beaten, and pretty much going through hell in the attempt to Make His Beloved Happy: "You trust me now?" Alice:
 * But to be fair to Alice, he certainly doesn't look or behave like a particularly trustworthy guy.
 * Kamen Rider Blade: All of Hajime's transformations come from being trusted. Really, all of them.
 * Kamen Rider Double takes this in an unusual direction: back Detective Jinno was apparently extremely easy to fool (even falling for the old Look Behind You! bit), but was so kind and earnest that it made the people who lied to him want to become better people so those lies became the truth. The flashbacks revealing this imply that this is what turned protagonist Shotaro Hidari from a juvenile delinquent into an honest man.
 * Mulder and Scully trust each other so closely and so intensely that if someone tells one of them something and the other contradicts it, they will pretty much believe the other without even thinking about it. Essentially, The X-Files is The Power of Trust turned Up to Eleven. The show's tagline is "Trust no one"--and they don't. Except each other, no matter what.
 * Not always, though, which since this trope is Up to Eleven, causes so much more hurt and confusion than it usually would. A big plot point in season six and part of season seven was Mulder trusting his ex-partner/ex-girlfriend Diana Fowley over Scully. Scully and the Lone Gunmen even had hard proof that she was working for the Big Bad, and Mulder refused to believe it. It almost caused the break-up of the partnership. Of course, that was what Diana Fowley had wanted all along.
 * Or the episode "Wetwired", where Scully is affected by subliminal messages on TV that Mulder betrayed her to the Cigarette-Smoking Man (Mulder himself is not affected "thanks" to his red-green color blindness). Seeing the trust they've built up to that point just go poof is extremely disturbing, almost traumatizing. Especially for Scully, once she snaps out of it.
 * In Supernatural's fifth season, Sam's (basically misplaced) trust in him is all that keeps Dean from going through with it after saying yes to Michael.
 * The slow, hard-earned building of trust between Inspector Lynley and his partner Barbara Havers is what makes watching The Inspector Lynley Mysteries worthwhile. Nathaniel Parker and Sharon Small sell the hell out of two absolutely broken people coming together against all odds and, through fire and flames, arguments and alcohol, learning to trust each other with no conditions, no questions, and no regrets. From that trust comes Character Development ahoy - Lynley becomes less snobbish, patronizing, and elitist and finally has one person who can look his dark side full in the face without flinching and make it lighter, and Barbara softens, opens, and blossoms and finally has one person who accepts her and loves her exactly as she is, fiery temper, deep insecurities, and all. Through it all they become one of the tightest-knit partnerships in the history of fictional law enforcement - oh, and sometimes they solve murders, too.
 * This is a huge theme of Merlin, particularly in regards to Prince Arthur's Character Arc. Essentially, every single person in his life has betrayed his trust at one point or another. His faithful servant Merlin is hiding the fact that he's a powerful sorcerer. His father lied about the circumstances of his mother's death. His half-sister betrayed him and tried to take over the kingdom. The court physician knows all the secrets of his life and reveals none of them. His uncle is plotting against him. His best knight is controlled by dark forces in order to seduce his future wife. Ironically, the one person that Arthur can trust is the character who is best known for her infamous betrayal: Guinevere. In this version she is caught kissing Lancelot on the night before her wedding to Arthur, but was under an enchantment at the time and had no intention of being anything but 100% faithful to Arthur.
 * Mrs O'Brian's childlike trust keep O'Brian and Kira chaste in Star Trek Deep Space Nine "Looking for Parmach in All the Wrong Places". In the end it is too much of a Kick the Dog for them to be able to betray it. The whole thing is mostly Played for Laughs (due to how uncomfortable the two of them are around each other) in the B-Plot of the episode.

 * Possibly touched upon in The World Ends With You. Neku is told repeatedly to trust his partner, and he does -- even when finding out that one of them was   That trust may have   Or maybe not, the ending was pretty Gainaxy. Anyone else know if this counts?
 * One of the main themes of Dissidia Final Fantasy is trusting one's friends. Special focus is given in Squall and Zidane's stories.
 * Played straight but twisted in Valkyrie Profile Covenant of the Plume. The plume can supercharge any member of your party into a walking engine of death, at the cost of their life following the battle. And it explicitly only works on permanent party members, who have come to trust Wylfred.
 * Phoenix Wright and Miles Edgeworth of Ace Attorney, in pretty much everything from midway through their second case together and beyond. Which is a very interesting display of trust, considering the fact that since Phoenix is a defense attorney and Miles is a prosecutor, one of them will have to lose whenever they're in court together.
 * Not at all. Phoenix's first priority is that the innocent are unharmed and absolved of guilt. Edgeworth's first priority is that the guilty are punished. These priorities are the farthest from mutually exclusive one can get, and as long as the truth comes out, both priorities are fulfilled and they both win in the way that truly counts.
 * In fact, in case they Take a Third Option.
 * "Zelos...I trust you." Lloyd saying this makes the difference between.
 * In Tokimeki Memorial 2, this is the pivotal trope of Kaori Yae's storyline. After a traumatic event in her past, she has lost all trust in both the others and herself. It's now up to you, the main protagonist, to help her regain her belief in The Power of Trust with the help of The Power of Love. As such, most of her events discuss about trust, and her Image Songs (like the verse in the Quotes' page) are heavily trust-themed.
 * In Baldurs Gate 2 Throne of Baal, can be redeemed if you trust him enough. Refusing to use a geas to compel his loyalty is the first step on his long road from Chaotic Evil to Chaotic Good.
 * ...I trust you, Shirley. And later, "Everything will be fine...I trust you."
 * Parodied in Portal 2 in which one of the advertisements shows that humans "cannot be trusted" to do cooperative tests with one another. Robots, on the other hand, can trust one another... for about 6 seconds longer than humans.
 * Essential to the relationship of a reyvateil and her partner in Ar tonelico: "diving" into a reyvateil's mental landscape is one big trust exercise in revealing her secrets to her partner, but also lets her craft and use more powerful song magic. Abusing a reyvateil's trust is a sure way to break and diminish her abilities. In the first game Misha invokes the trope directly whenever Lyner protects her from an enemy attack: "I trust you!"
 * Left 4 Dead: this is the only way to win the game.
 * In Persona 4, Naoto Shirogane's belief in this trope is exemplified by her decision to get herself attacked by the killer: She is completely willing to trust the Investigation Team to save her, even though her belief that they have the power to do so at all is only a guess. Subverted when the Investigation Team utterly blasts her for this, pointing out that if they had failed, she would be dead.
 * Fire Emblem Tellius: Path of Radiance and Radiant Dawn have their support conversations, which allow for power-ups when near the other character supporting you. Can be used for a Back-to-Back Badasses moment if done right. Also, subverted in Tibarn's conversation with Naesala, where the former states that he trusts the latter because they both have the same goal. What does Naesala do? so it's at least a slightly averted subversion.

 * Teen Titans provides some negative examples. When Robin tries to get Slade's trust as Red X so they can meet, he is Out-Gambitted. Slade notes, "Trust is easy to destroy, but it takes time to build." Terra happily exclaims the Titans trust her. That doesn't end well. In an episode titled "Trust", Robin ends up giving a communicator to "Hotspot". That was actually a Nice Job Breaking It, Hero moment, since it was really Madame Rogue.

Real Life

 * In philosophy, The Iterated Prisoners Dilemma dictates that in the long run, it's better to trust your fellow human beings than try to screw them to get yourself out of trouble. The criminals code against snitching works on this premise, don't snitch today, tomorrow it might be you who they're asking about. The original Prisoner's Dilemma arrives at a different conclusion...
 * The "tit for tat" strategy essentially says that you should trust the others until they give you a reason not to. If they betray your trust, then retaliate, but also be quick to forgive.
 * "Tit for tat" is a simple strategy - always do what your opponent did last time. It fared better than any strategy it was put against in computer simulations.
 * Newly conquered people should be left their weapons They will, after all, need to defend themselves, and while disarming them will slow rebellion, it will not stop it since they will be able to get arms somehow, and the good will generated by this trust is better against rebellion than the delay. Who thinks so? Why Niccolo Machiavelli. In The Prince, no less.
 * In Systems of Survival Jane Jacobs observes that one of the greatest imperatives for a healthy civilization is for traders(people with "productive" occupations such as farmers, merchants, artisans, etc) to instinctively trust the honesty of others and "guardians"(people with protective occupations such as soldiers, police, firemen, etc)to instinctively trust each other's loyalty. When you think about it, it is amazing how no one asks waiters whether the coffee they buy is poisoned, and it is possible to buy and sell Amazon without seeing the other party; and how, at least in a few countries, it is possible to hold an election without the losing party being mass-purged to prevent the need for another election and without a military coup being a serious possibility.
