He made a bit of a sarcastic face at her-- you know, the kind that expressed ha, ha, very funny without speaking a single damn word. "One, I'm not a thief. Two, the city is a lot different than upstate. Three--" He hesitated a moment, shaking his head a bit as he reached up to rub at his eyes. The dizziness from the painkillers and most likely the fever never helped his cause. Ever. And the fact that she was frustrating him a little more than he would have liked.
Damnit.
"Three," He pointed at her, finally, "I probably should have never come back here," to the city, he meant. Things had only gone down hill from the moment he and the bastard rookie had arrived.
O'Brien was usually a pretty confident guy, but right now, he was pretty damn sure that he couldn't take her. He wasn't feeling his best, and desperation reigned supreme in his reasoning for being so willingly agreeable.
When the woman lifted the flashlight up again, he brought his arm back up to try and shield his eyes, turning his head just a bit. Quarantine Guy...? Seriously? His brows furrowed, "what do you mean? I Can't be the only guy in Quarantine." Or could he? Or the only obnoxious one, maybe. He scrunched up his nose, nodding a bit, "Yeah. I guess. Yes. Do I know you?" He dropped his arm, turning his attention back to her.
Oh good. A machete. It was confirmed. He gave her a nod, "nice. I'm impressed," no, seriously. He was. And he wasn't going to threaten her. He managed a smile when she laughed-- but it was gone as quickly as it had arrived, thanks to her threat. Considering the fact that he really wanted to keep his balls, he didn't argue.
But as soon as he turned to start toward the back, he couldn't keep from smiling again, this time a bit proudly since she admitted to liking the sound of Miss Machete. Yeah, he came up with that. Miss Machete. She liked it. That was good.
He wasn't going to yell surprise. He wasn't going to yell at all. Glancing back over his shoulder for her a moment, he looked ahead again, "thanks for the light." He paused, "and since I've already been stabbed in the back once this month, and don't feel like going through that again, is it alright if I get my gun again? I'm on the front line, here. Might save you a slice or two, if a zombie jumps out, and I put a bullet in it's head."
