Like always, Draco found himself amused by Montgomery. Well, at least this one. She had a knack for saying amusing things, and doing so in a moderately less annoying way. Well, except for when she got it in her mind there was something between him and Harry. That had been highly annoying. But other than that? She'd been relatively harmless.
"Alas, I fail at hiding in plain sight. How very disappointing." It was said sarcastically, as he knew this disguise suited him good. Hiding in plain sight. Not to say that he wasn't recognized from time to time, but it was usually by someone who had a pretty goo understanding and knowing about him. He didn't put it past her to figure it out, she was a Ravenclaw after all. But he was hardly terrified over Alexandra Montgomery finding out Draco Malfoy was at the Hog's Head.
"I think you will find 'who are you not hiding from?' to be a much better question." He took another drink from his tankard, draining what little was left and holding it up, signaling for more. His tankard promptly refilled.
