Time crave

More of the “Chara likes to pretend to be Frisk’s older sibling” headcanon. I can see them trying to force the kid sibling/older sibling dynamic on Frisk at first, as a way to manipulate and control them, but over time, Chara kind of forgets why they’re being so nice and protective of their vessel, and looking after Frisk and trying to make the journey through the underground as bearable as possible just becomes routine.
 They’re probably singing one of Toriel’s old lullabies.

“The truth, is that you’re here because you wanted to feel like something you’re not: A hero. I’m here because you can’t accept what you’ve done. It broke you. You needed someone to blame, so you cast it on me. A dead man. I know the truth is hard to hear, but it’s time. You’re all that’s left and we can’t live this lie forever. I’m going to count to five, then I’m pulling the trigger.”
