The Chinese was enough to make Cox's eyebrows raise briefly before he turned to face her completely, settling in a comfortable stance despite how cold he was and how much he wanted to keep moving. Oh, she'd spoken to him now, and he always got the last say. Besides, he was annoyed, and the bubbling anger needed an outlet, and right now Zoe was the only one near enough to serve as a target.
Her first comment in English made him cock his head a little, that annoyance snapping a few more threads of control. Of course, there was one rule for Perry Cox and another for everyone else, and despite how he treated people, he didn't like to be talked to like that.
"Ohhhhhhh-kay, I'm gonna just go right ahead and pretend you didn't just call me that..." He hated that. 'Doc'. It was so derogatory, that and it reminded him of Bugs Bunny.
"And then I'm gonna go ahead another step and try to confirm with you exactly what business that is of yours, considering I don't know you, never will, and don't exactly care to. N'kay? Now why don't you run along back to whichever shelter you came from -" He was obviously slating the large, bulky coat she was wearing, "- and cross your little frostbitten fingers that they didn't already hand over your daily helping of soup and smack cakes to someone else."
Honestly, he felt better for that, and of course he didn't exactly care that he was insulting a complete stranger. He didn't usually give a crap, and when he was too concerned with where he was and why (especially considering it was snowing, which actually scared him a little, because that had to mean he was further from his apartment than he cared to think), he cared even less. Panic was starting to build in his chest at just to what lengths whoever it was had gone to to prank him, and the arrogance in his mind was working overtime to turn that weak feeling of helplessness into rage, something he could deal with a lot easier.
