John was taken back when Richie gave him the wrap. Richie was obviously very cold but it was telling of his character. Since it was better to have someone watching your back, someone who had been here longer than himself. He didn't need the wrap but didn't feel like rhyming out a long winded 'I'm fine, thanks'. Instead his face softened as he dipped his head in thanks. No, he wasn't going to try and draw that one out either.
"Thank you that is very kind, I won't keep it long so pay no mind." He was all for finding a better place to sleep. Or a place to sleep at all. Having an ally to watch your back for some rest was extremely underrated. "Once we find some place that is decent and warm--I'll take the first watch, and wake you to warn."
