Of course she did. He nodded to her flat reply and gave a bit more of a look around. And yeah, yeah, okay. So what if he was the chatty type? There may have been a little blood, but nothing too drastic. He'd need to reapply a new bandage, when he got back to the Library, but he'd eventually have to do that anyway.
And she didn't have to worry; O'Brien wasn't expecting anything from her. She'd already done plenty, even if it was not without complaint or griping. He glanced down, thinking quietly on her statement about having already been to City Hall by now. It was more than likely true. He wasn't moving nearly as fast as she most likely would have liked.
He was just about to tell her she didn't have to hang around and wait for him, when she admitted to not leaving people behind. Unless they deserved it. And she said that he didn't. Which made him feel slightly less of a nuisance. But he knew, to her, he still was one.
"Well, I appreciate it," he watched her, his eyes curiously moving over her as she gazed up at the night sky. He kept his attention on her even as she started back over to take her bottle of water back.
He was still holding his side, because yeah, it still kind of hurt, and he must have looked like crap for her to ask if he was going to pass out. His brows lifted with a bit of surprise at her questions, and he straightened up a little. He winced the tiniest bit, "that's a good question. I hope not.. but I make no guarantees..."
He nodded, "It would probably suit me right for you to leave me, if I passed out on you. It happened the other day-- Me passing out, I mean. I was at a department store, trying to find a coat. I'm not sure how long I was out, but I was lucky no zombies found me."
