Gargoyles/Heartwarming

• Goliath and Elisa dancing in "Eye of the Beholder." It's just too sweet for words.
• When Goliath helps Elisa back to her feet and the pair hold hands and smile while Goliath is still (temporarily) human in "The Mirror".
• A lot of pieces in a series this long, but of particular note:

Princess Katherine: "He'll hunt us to the ends of the earth!"
Magus: "*gentle/sincere smile* Then I'll take you beyond them." (And he does.)

• The end of "Mark Of The Panther" also.

Goliath: Your quick thinking helped us defeat Anansi. I am proud of you, my daughter.
Angela: Oh, father! (hugs Goliath right before they turn to stone.)

• The end of the episode "The Cage": Elisa takes Derek to see their parents, whose shock at his mutated state lasts about a few seconds before they rush over and tearfully embrace him. Following up from the massive Downer Ending of "Metamorphasis", it's VERY pleasing to watch.
• "Hunter's Moon"'s conclusion:

Elisa: "You know how I feel about you, right?"
Goliath: "How we both feel... Yes."
Elisa: "Good." (leaps up to him and gives him a kiss)

• Strangely, Xanatos and Fox's relationship counts as this for this troper.
• In "Eye of the Beholder" when it becomes apparent that Xanatos was really trying to save Fox and not simply retrieve the Eye of Odin.
• Xanatos and his father in "The Gathering: Part Two." "We haven't always seen eye to eye, but I've never been more proud to be your father."
  • Xanatos' was similarly sweet, if to the point: "Thanks, Pop."
• In the very first episode, the gargoyles explain that they don't have names:

Tom: But what do you call each other?
Brooklyn: "Friend."

• The Manhattan Clan's reunion in "The Gathering, Part 1."

Lexington: I can't believe you're finally home!
Brooklyn: Welcome back!

• • Also, Hudson after being told there are other Gargoyle clans out there in the world:

"We're not the last. We're not alone."

• Lexington's (facial) reaction to finding out that Amp is single. He's so happy....
• Baby Alex playing on the floor with Bronx and gleefully calling him "Doggie!" while Lex and Fox awkwardly make up because they have something in common: they both care about Alex.
• Rather subtle, but learning that Xanatos chose Owen over one wish from Puck speaks a lot about the relationship of these two.
• A blink-and-you'll-miss-it moment from The Price. All of the clan, except Goliath, end up stranded on a roof at the mercy of Macbeth (or so they think), who is on a hovercycle and has a laser gun. There is no way they can escape without getting shot. Hudson jumps in front of the trio and flares out his wings, blocking them from view and making himself a bigger target, fully willing to die if it means the rest of his clan has a chance of survival.
