John had decided somewhere between getting a worldhop and arriving in Cardiff that he wasn't going to bring up anything about last night. For one, he didn't even remember what had happened, and besides. He felt he'd given as good as he got, and that they should probably let bygones be bygones. After all, he was letting the other man make him coffee.

"Yeah, not much help there, sorry," he said, "And. Charming's one word you'd never hear describe Sherlock, that's for sure." At Ianto's comment about having found him, John looked around before noticing the brief wave from the taller, definitely younger man. Why was everyone so much taller than him? It simply wasn't fair. Ah well. "Right," he said, giving a half-wave back, because it was only polite. Also, it distracted him from the fact that they'd hit the awkward point of the conversation, where they could see each other but still not hear each other.
