The X-Files/Tear Jerker

""The world didn't end...""
 * The episode where Scully's cancer is diagnosed is a direct and shameless heartstring-twister from start to finish. It works.
 * The scene in Redux II where Scully tries to get Mulder to pin the death of a man he killed on her - because she doesn't want him to go to prison, and she's going to die soon anyway. The look on Mulder's face is just heartbreaking.
 * The Unnatural, baseball, fun loving aliens, the gospel and song and finally  It's just blood .
 * The last twenty minutes of "Emily."
 * The ending of the episode "The Post-Modern Prometheus".
 * The end of "Millennium"..

"Rob Roberts: I can't be something that I'm not."
 * The final scene of "Existence".
 * The episode "Trustno1", especially the e-mails between Mulder and Scully (poor Mulder just wants to come home) always make this troper tear up.
 * And let's not forget the tear-jerking scenes from the "Within/Without" episodes, notably when Scully goes to Mulder's apartment, finds his shirt and falls asleep on his bed clutching it tightly.
 * The episode "Roland" was heartrending, especially the end where Roland leaves his home and gives Tracy his jar with the stars.
 * The end of "Closure," where Mulder finally comes to terms with Samantha's disappearance. The fact that this Moby song is playing in the background probably increases the sadness tenfold.
 * Whenever Scully breaks up, chances are it's going to be a Tear Jerker. Just look at the ending of "Irresistible".
 * The ending of "Release", with Doggett and his wife spreading  ashes into the ocean.
 * Pretty much all of "Kaddish" especially the story behind the wedding ring.
 * When Doggett's amnesia in "John Doe" gets broken by the memory of his murdered son. It's the only time we ever see him cry.
 * The ending of "Hungry".
