You keep saying that, but it doesn't mean anything except a possibility unless something forces your hand! Just because something can happen doesn't mean it will. There's so much else you can do with your power... even without it, you help people.

He'd been so distressed for her fate, but stupidly he hadn't bothered to question the source of it before now. He'd imagined the dying world she described, floating continents made of massive creatures, struggling and falling out of the sky, and some elaborate... mystery that required her life to power and salvage that world. Fix the Titans, or give them a land beneath to fall upon safely. He hadn't thought about it, had only thought how awful it was that another world had to be saved through something like that. He'd felt angry at whatever must have directed her towards this fate. How dare they choose her, someone so kind and loving who didn't deserve to die, who could help so many more, who has more power hiding inside her than he could fathom, if this is what she fears it'll do. How dare they.

But... it's her. She's deciding herself, unprompted. So now he can't help feeling angry at her choice instead.]

If you want to live, then live. Fight for it with everything you've got. If your powers are the problem, seal them, not yourself. Save the world by watching over it!
