"I don't know," Adora replies, expression pinched.

She thinks she does know, but she also can't let herself choose. She can't let herself be selfish, because the world - the universe - needs her and she can't give up on it. She can't chose for herself. She's never tried to be selfish. It's how she is. She gives and she gives and she gives until she's empty and then she keeps trying.

And she's also probably lowkey suicidal, but that's another story.
