Jon tries not to look away and manages for all of a few moments before glancing to the side. If he wasn't feeling guilty as all shit on top of at least ten other emotions he'd probably be baffled at how intense Martin could be. It was kind of impressive? He was kind of proud of him? Probably not the best time to say that, so he nods, though the relief doesn't make him look as contrite as he probably should.

"... it's not that bad." He holds said hand to his chest but he does take a seat, probably rather famished because seriously, what the fuck was he eating for five days with what he had on hand? He pulls one of the sandwiches over, annoyed at doing everything one handed neatly and eventually giving up on it not being a bit of a mess. He is tired and starving and on his last rope, enjoy mutilation sandwich.
