To put things very lightly, Theodore generally hated pubs. It was only out of extreme boredom and a dangerous sort of sick curiosity that he had accepted Demelza's offer, and even then he was hesitant. He didn't understand people that were so effortlessly nice. He always looked for some sort of ulterior motive that would put them ahead, and in Demelza's case, Theodore could only fathom the criticism she would receive for associating with him. After all, he was the quiet, mysterious loner sort - not really the type that one would readily socialize with. And Demelza had invited him out. To a pub. Sounded date-ish, didn't it? Theodore was sure that this was purely an awkward social call, but it was highly likely that people would talk.
When Theodore entered The Brazen Unicorn for the first time, he had instantly decided that he didn't like it. First of all, he quickly picked up on the reoccurring muggle theme throughout the pub, and almost immediately felt like a bit of an outsider. He knew so little about the culture that was not his own, and he wasn't really willing to bend in order to discover it, either. For one, it had nothing to do with him, but more importantly, he found it depressing and confusing. A world without magic was not one he was eager to delve into. In addition to this, the fact that people were dancing in this pub brought a second set of concerns to the forefront of his mind. All he could do was hope that Demelza didn't like dancing, or at the very least, didn't expect him to partake in it.
When Theodore spotted the girl, he felt a touch of anxiety wash away. It was no secret that he was terribly anti-social in a crowded setting such as this, and he was already having second thoughts about agreeing to come here. Everything was too loud and people were packed too tight. In fact, the mere act of crossing the pub and get to Demelza involved Theodore rubbing against a few strangers on the way by, and he really hated touching people he didn't know. He was such a mess when out of his element.
"I thought less people would be out on a Sunday night," Theodore 'greeted', sliding up beside Demelza at the bar and leaning against the counter. He thought better of his decision almost instantly and wrinkled his nose in the most prissy fashion, straightening up again and rubbing imaginary filth off of his elbow. A least he'd warn all black - if the place rubbed off on him, it would be less visible. Getting over himself quickly, Theodore took a moment to regard Demelza a little more closely, his eyes slightly narrowed and watching her as though trying to read her thoughts. He was still trying to figure out this invite. "I hope you didn't come here to dance."
