[He does get it--that was one of the earliest things they'd bonded over, after the kids they had to watch out for. They're both people who need to find somewhere they're needed and give themselves over to that. But the difference, perhaps, is that while the reasons Break has found to exist have changed throughout his life, he's always had one in some form or another.

...Back then, though, it was different. All I ever knew before Beacon was how to survive. When you've got nothing else, you think that's enough, you know?

[He shakes his head, letting out an almost wistful-sounding hum.]

Think teaching people like me how to live helped remind him that it all mattered. That there were still things in the world worth fighting for.
