Given the immediate sounds of confusion Emrys could hear around him, slipping away before anything got out of hand seemed to be exactly the order of the day. He turned and started to head vaguely in the direction that the entrance to the Museum of Magical Miscellany had been, before he'd been unceremoniously removed from it. Apparating out of the middle of a crowd of Muggles was bound to cause trouble, but if he could find his way back to the Museum he could use the floo in their lobby. Failing that, he supposed he'd have to just go outside and hope for the best. He didn't know, after all, if the Museum was still here, or whether the entrance had moved along with the room that he'd been in. If that was the case, he might fare better just walking out and finding his way back to Diagon Alley.

While luckily no one had taken an immediate notice to him, it seemed that another Museum patron up ahead had not been so lucky. Emrys was inclined to just leave it be and keep his own head down, but it was a girl — and one who didn't look very well equipped to handle herself in a strange situation, at that.

"Sorry," he said, inserting himself into the conversation with the Muggle man and taking the young redhead by the arm as though they'd arrived together. "She wanders," he explained to the man, then made a face as if to indicate that the girl wasn't all there. Easiest way to get out of a conversation you didn't want to be in, in his experience; bring up something that the other party wasn't comfortable with. For most people, mental disabilities fit the bill rather neatly.
