"Saw that did you?" He raised an eyebrow again. He'd only made the most subtle movement of his hand, he hadn't actually pulled the weapon. It still remained concealed. But he was not stupid to go out without carrying. Though it may yet do him little good if Moriarty did decide to have him shot. "If you are not armed you are in danger just being around me." He knew Moriarty wanted him to isolate, but at that time he really didn't care. He wanted time away from the inn. His friends tried to help but they could only do so much, he needed to be able to breathe too. There were only a couple of them who truly understood what that man had put him through. Twice now.
He wasn't about to talk about him a third time. He shrugged off the comment about Eponine. "I've dealt with Moriarty more than most here have. To not be armed would be suicidal." Not that he cared much about that right in this moment really. "I'm not looking for any duels at dawn." He commented off handedly and frowned a little. He should have been able to strike up any conversation, that's what he was there for. To talk when Sherlock didn't want to, or wouldn't and yet he found himself wordless.
"I'm sorry..I don't think I make great company at the moment. Suppose if you are unarmed I ought to walk you back though." That would be the right thing to do, he had been in contact with him. John wasn't sure what tricks Moriarty had up his sleeve.
