Heartwarming / Ask Drunk Chara

• There’s something very sweet about Chara and Sans not only making up in this verse, but even becoming close enough that Chara is happy for Sans to marry Toriel and become their stepdad. Considering the history between those two, it’s both surprising and deeply heartwarming.
• Chara, of all people, actually being the one to convince Sans to ask Toriel for her hand in the first place.
• Underfell!Sans making peace with Frisk and even shyly wishing them farewell when they have to leave the Underfell universe.
• Upon the reveal of Gaster in the void, askers start sending him things, such as his own 'alive' Beery the Beer plushie, pizza, blanket and 3DS. Gaster, never saying a word, is clearly happy with this development.
