"It was sarcasm, Jon. I was being sarcastic." Martin does finally look up at least, and he's angry and upset and worried out of his head all at the same time. Tired, too, because at least when he was trying to keep the Archives running before he knew Jon was safe back at his place.

The past week, though, had offered no respite from the stress. Just the plain and heavy fear that wherever Jon had gone, it hadn't been good.

"Well, I'm just- I'm glad you decided to leave without a note. Better than you being kidnapped, I guess." Perhaps there's a little acid in his voice, but he can't help himself. Jon's hurt; he knows that his own upset feelings are going to take a backseat to worry very soon, so he's letting himself indulge now. Just for a minute.
