It was probably a good thing that she didn't catch-- or comment on, or pick on him about saying that he'd killed the zombie for her. Even he hadn't really realized he'd said it. And whatever anyway.
His brows went up in surprise when Leah swiftly turned to stomp on the back of the zombie's neck. Damn. Yeah, it was settled. This chick was hot. And kickass. Hot because she was kickass. She had a pretty face too-- whether she'd agree or not. And yeah, yeah, okay.. maybe there was something about that negative personality of hers that he liked too. She could tone down his ridiculous positive-ness.
"You would have liked that," he started, "at least then you wouldn't have had to worry about the horde, since I attracted them with my loudness." He pursed his lips at her comment about dying faster, and opted not to comment on it. He really didn't want to die. Not yet. And he didn't want her to die today, on his watch, either.
And he wasn't moving that quickly. He felt a bit bad about it. But it kind of hurt every time he reached up and pulled himself up to the next rung. Fantastic. At least he had plenty of painkillers to take if and when he got back to the library.
"On it," he called back down at her, aiming for the zombie creeping entirely too close to her back-- the very idea made him cringe, considering his own worst bite was on the back of his shoulder, and he remembered all too well being bitten and tackled from behind. He fired a bullet into the top of the zombie's head and then quickly tucked his gun back into his holster so he could reach for the ladder, "Hold on," okay, yeah. He didn't know if zombies could climb ladders... he'd never actually seen if one could or not, but he wouldn't put it past them. So if the ladder was going to come back up anyway (so they wouldn't be followed), he might as well try to tug it back up with Leah on it.
Unfortunately, he wasn't Hercules, though, so it wasn't as easy as he'd imagined in his head. If he were Batman, maybe. But he was just Quarantine Guy, and it was more likely that Miss Machete could take better care of herself than even he could. But he was going to try and help get her pulled up at least high enough to get out of the initial reach of the horde.
