The X-Files/Heartwarming

""I have never met anyone so passionate and dedicated to a belief as you. It's so intense that sometimes it's blinding. But there are others who are watching you, who know what I know, and... *Beat* Whereas I can respect and admire your passion, they will use it against you. Mulder, the truth is out there. But so are lies.""
 * Mulder and Scully having an impromptu slow-dance at the very end of the "The Post-Modern Prometheus". That the episode itself was something of a CMOA for the season or series which earned it seven Emmy nominations and a parade of rave reviews enhances the good feeling. David Duchovny would go on to say that whatever came after, for him, that one moment would always remain his favorite.
 * "The Unnatural" is just one long CMOH.
 * Scully's passionate speech to Mulder in the first season episode "E.B.E." is so unexpected coming from her but also completely natural after all they've been through together.

"Mulder: I'm sorry, I, uh... I couldn't let you risk your life on this. Scully: Did you find what you were looking for? Mulder: No. But I found something I thought I'd lost. (looks at her, then takes her hand) Faith to keep looking."
 * And the best part of it? The next scene reveals that Mulder has agreed with her in his own Tsundere way. It also marks the point where Scully becomes the only person Mulder trusts (and vice versa).
 * "Folie a Deux", and Mulder telling Scully she's his "one in five billion".
 * This troper also considered her final line of "Folie a duex: a madness shared by two" to be a hint at something else shared by two.
 * Scully singing Three Dog Night's "Joy to the World" to a concussed Mulder.
 * This gets an adorable Call Back when Scully amends the song for her baby: "William was a bullfrog..."
 * From "End Game":

"Mulder: Dana... after all you’ve seen, after all the evidence…why can’t you believe? Scully: I’m afraid. I’m afraid to believe. Mulder: You couldn’t face that fear? Even if it meant never knowing what your father wanted to tell you? Scully: But I do know. Mulder: How? (Beat) Scully: He was my father."
 * From the second film, there's Skinner hugging Mulder to keep him warm.
 * The seventh season episode "Requim" has the totally adorable cuddling scene.
 * The ending of "Beyond The Sea".


 * Mulder's speech to Scully in the hallway of his apartment building in "Fight the Future."
 * Mulder and Scully being cute with Baby William at the end of "Existence."
 * The "touchstone" speech from "The Sixth Extinction: Amor Fati."
