[It's easier to know something when it's just in your mind, all the connections already made. Harder to understand it as it's own thing, as it's own presence. Martin isn't thinking about it right now, not when Jon is here and warm in his arms, not when he has the chance to feel this instead of the damp, cloying mist of the fog on his skin.]

Yeah, it-- it has to be. I mean, I... I don't know. I didn't think a lot about it, during the apocalypse. I wasn't affected like you were, so I thought it wouldn't...

[He just sort of shrugs.]

I don't know what I thought. Taking care of you is more important anyway. Any way I can... do that, really. If I can.
