It's a question he's spent a fair amount of time considering without reaching an answer. How could he possibly know? They're neither alive nor dead but something in between, and while he hopes that means they might have reached some unexpected equilibrium between the two, hopes shouldn't be though of as certain reality.

"I don't know," he settles on saying even if it's an unsatisfying answer. "Everything that's alive dies some day, but we've already done that. I guess I'm going to go on like I'm living until something slows me down."

Better not be any time soon, he thinks as he curls an arm around Will. He has a lot of living he still wants to do.
