"Well, would you be friends with an asshole that shot you?" He rolled his eyes, "fine. Yeah, I considered the guy a friend, and look what happened." He stared at her while she explained what she would do in his situation. He was just about to comment on shooting someone--and as payback, at that-- when she started making assumptions as to what kind of cop he was again.
His brows pushed together with frustration; Actually. He didn't know what to say to that. A 'happy-go-lucky kind of cop'? That was an easy target for betrayal? "I'm not happy-go-lucky," but an easy target for betrayal? Maybe... It was highly likely actually.
He narrowed his eyes a bit, thinking quietly at what she had said, and then cut his attention back up to her, "We've been over that, remember? I don't know you at all. I don't even know your real name-- so clearly I think you're useful to have around. And pretty," okay, yeah. He said it.
"It's going to suck," because running wasn't exactly something he was going to be good at, in the shape he was in. Fuuuuck, it was going to suck. O'Brien moved to climb back up into the window to follow Leah's footsteps, hopping back down onto the sidewalk. "You're positive? How far is City Hall from here, again?" He huffed, giving her a nod, "I can cover you, and I promise not to sacrifice you. It's not my style."
He paused, quirking a brow at her offering up one of her machetes to him, and it actually made him smile a bit. "Deal," he gave her a nod, and stepped past her to lift his arm back up to aim out toward one of the zombie hookers to shoot her -- well, in the face. Headshot. the only way to kill a zombie, really.
And for the record, yeah, he only had a little bit of ammo. He'd had everything stolen, been locked up in Quarantine, and only just now got out because he basically snuck out, but not without getting his gun back first.
