Deadly Premonition/Fridge

Fridge Brilliance

York's invisible friend Zach is actually you, the player.
- Quite the observation. Wouldn't you agree, York?
When York opens a door, he quickly looks around before going in. Why? To look for any threats before actually going in. Looks like he has been jumped before.
- Becomes even more brilliant when you see the flashback to when Kaysen attacked Zach's family. Zach was watching from a doorway where he couldn't immediately see Kaysen, so York's cautiousness is a defense mechanism for his trauma as well.
  - Not only that, but York's signature mannerism of putting two fingers to his temple while saying "Don't you agree, Zach?" is him mimicking his father's last words and actions before shooting himself in the head.
Kaysen's final form makes sense: he doesn't need to look like a monster to be a monster.

Fridge Logic

When you are at the final battle, Zach ends up running DOWN a whole flight of circular stairs away from Kaysen, only to end up at the TOP of the roof of the clock tower... huh?
- Well, given that Kaysen is implied to be an Eldritch Abomination, and he might very well be warping space-time, combined with the whole Through the Eyes of Madness thing in the dark world, there's at least two reasons why this might have happened.
In Spy Fiction, Kaysen is killed by Lauder. This never made any sense to me because he was still alive back when the gas was released meaning he was super paranormal for a while. If that's the case, how did the Lauder kill him? If the Lauder did kill him, either the events of Greenvale shouldn't happen, or Spy Fiction took place after Deadly Premonition and never happen because Zach killed Kaysen.
- This is because Kaysen is part of SWERY 65's Reused Character Design group. Deadly Premonition and Spy Fiction are not canon to one another. The same thing goes for General too, who was eaten by Pirhannas.
During the second victims death York just stands there watching her die. Alright he made a mistake assuming she was dead the first time I can forgive that (although he does the same damn thing for the third victim too) but after seeing she was alive and after the trap had been sprung he didn't think, maybe he should attempt to support her weight to stop her strangling to death two feet in front of him. Don't say it was an instant death either, we clearly see her still alive even before York starts seeing things from behold the grave.
If Polly has a picture of Kaysen 50 years ago, why doesn't she wonder why he still looks the same?
- Maybe she's forgetful.
  - She's also an alien? Knows about the red seeds? She grows her own saplings?

Fridge Horror

Given the method we see for creating red tree saplings, does that mean there's someone buried in a shallow grave under George's lawn?
- That's just the methods to get the seeds to sprout. After becoming saplings, they can be planted like regular trees.
- Although that's not the only Fridge Horror at George's house. Remember his mother's corpse in the basement? Kaysen most likely raped her. Is that why George become so fanatic about the red trees?
Pay close attention to Brian Xander Morgan's gun: it's a magnum, now take note the prize in Willie's Doghouse after completing his sidequest with all seven bones, a magnum. Kaysen likely stole that Magnum from Xander's dead body.
