Luckily for Sebastian, Oliver didn't ask for an explanation as he was already too busy being confused by everything else he'd said. "But what do you mean? I mean...how...what..." He gestured vaguely, struggling for words.

Then he decided it was better to stop attempting to ask questions for a second and think about this. He had seen Sebastian talking to an empty seat, after all. If Sebastian was here with a friend, it was a friend Oliver couldn't see, and it definitely wasn't someone he'd heard of around the Plane yet. So what did that mean? "Sebastian, where are you?" he asked instead. "I mean...is this one of those merger things?"

That gave him an idea, and he glanced around the pub again. No one seemed any more bothered about Sebastian than they had before, but there were a few patrons--and one bartender--giving Oliver odd looks now. His eyes widened, and he reached for his ear, pretending to fiddle with a non-existent earpiece. "They can't see you, can they?" he whispered, trying to work out if there was a way to tilt this situation so he wouldn't come out looking crazy.
