"I don't know."

Cole doesn't. He doesn't lie, doesn't really know how to, and he doesn't know. "I can't see the future, not like that. But it would probably be more comfortable to learn how to live with yourself and Them, because that's a thing you can do and it doesn't matter if you have Them in the future or not."

Cole doesn't know how to make it happen, how to be okay with it all, but he knows it's the best way forward for Ben.
