House of Anubis/Heartwarming

Patricia apologizing to Nina, followed by Nina responding that she forgives Patricia, as Nina understands that Patricia acted the way she did only because she was worried about Joy.
Alfie returning Amber's dress after Jerome pulled a prank on her by stealing it
Nina and Fabian finally getting together at the end of the season finale. They had been (ship)teased so much, as well as interrupted a number of times, so seeing them kiss and smile in bliss afterward is worthy of this trope.
When Victor finds out Vera's non-stone Taken for Granite state, and is threatened to return the other 3 items the kids need, he does it with little to no hesitation on his part. In fact, he even puts them in easy-to-find places and outright lets the kids take them from him. He even planted a small kiss on Vera's forehead, when he thought he had failed her.
When Nina is captured in the Sennet game, the whole gang is understandably upset about this, but who was the most gung-ho about getting her back? Patricia, to the point where she was eager to go back and play the game right away, despite the risk to all of their lives. That's right, the girl who hated Nina when she first arrived is now the most insistent about getting her back.
Victor Rodenmaar Sr's final request to Nina:

Victor: Pass my message to my worthless son. Tell him I'm sorry...and that I was the worthless one.

- And afterward, Nina giving Victor the message from his father. The look on his face afterward, and the way he looks like he's about to cry, truly makes you feel sorry for this guy.
Victor giving up the last Tear of Gold, the missing indregient for his immortality exilir recipe (which he's been looking for the entire season), to revive the dying Joy. It shows that despite his ways, he truly does care for the kids.
- Speaking of Joy, her Heroic Sacrifice by taking the fatal lightning bolt that was meant for Fabian.
A small one compared to the others, but when Victor encourages Nina to give Rufus the mask, he calls her "Nina". Not "Nina Martin" or "Miss Martin", just "Nina". For him, that's showing a great deal of warmth.
