It sounded as though the place would have Theo on high alert, but it didn't sound as bad as he thought it might from the way Ernie described it. He knew enough spells and hexes to keep himself from being buffeted and poked around too much as well, even if he did tend to be a bit loathe to use them in public as they could actually draw more attention to the fact that he didn't want to be touched and crowded sometimes.
He was aware of their surroundings enough that he didn't jump when the tray came to their table and he likewise took his drink and took a sip, his ever-present warning spell not alerting him to any poisons or potions that might be in his drink; Theo really took paranoia to a new level. Ernie offered to accompany him to a Blues night at this place and really he would feel a lot better going with someone he somewhat trusted rather than going on his own, especially if the place would be loud. It didn't dawn on him that Ernie could be asking him on a date. "Yeah, it could be, I'd like to do that." he agreed that semi-awkward smile responding to Ernie's unsure expression.
