Rachel rests assured in the knowledge of one thing: she didn't die until she chose to. Luck and skill and determination got her through a war until she chose to stop fighting. That might not mean it will happen like that again, but... well, Rachel's not sure it doesn't mean exactly that.

She glares at him.

"I'm going back in. And again and again until this is done. This is what I do, Tobias."

It's like asking him to give up his wings, asking her not to fight.
