Yes. And there is a saying about accepting the hand you are dealt with, is there not?

[ Oh, immortality's a pretty crappy superpower if you have to watch everyone you've ever loved die or turn against you. Clearly Booker is a man who has accepted his hand and is dealing with it just fine.

But his immortality has never really been a power so much as a state of his existence. His actual newfound power on the other hand ... well, he hasn't touched that since he arrived here. ]

What power are you trying to summon right now?
