It does surprise Jon, though that's quickly turned to sympathy and his old pal, guilt over bad decisions. He starts to walk over, stops, then nods. "I won't. I'd rather stay."

After a few moments of waffling over it he approaches, reaching tentatively to touch Martin's jaw with his good hand. It's pretty clear he wants more, he'd love nothing more than to drag Martin unsexily to bed and just stay there for a few days. Of course he's far too gross for that, and given everything he wasn't sure how welcomed any of that would be, so he just swallows and nods again. "Shower, right."
