Don't do me any favors, he thought to himself as she begrudgingly took on the responsibility for his protect. He was starting to rethink his idea that he was too wobbly to be a match for anyone. He figured that if it came down to it, he could protect them both. He'd been fine when he was walking before after all. It had just been when he'd stopped that he'd lost his balance so badly. Or maybe they'd injected him with something that hit in waves. Who knew? Whatever though, he wasn't going to argue with her.
His foot throbbed now and the tattoo was begging to be scratched. Whatever he'd been on the trail of remembering a moment ago slid cleanly from his mind. The more he tried to remember it the more vague it became until he gave up trying to remember altogether. It made him want to kick the booth again but he was done being out of control. He zipped his anger back into place and swallowed it down along with some of his pride. When she put her arm around his waist and pulled his arm around her shoulder he didn't resist. Instead he leaned slightly against her, careful not to put a lot of his weight on her, and allowed her to pull him away from the booth.
Out of steam, he relaxed and wondered briefly if he should be trusting her but that was a stupid thing to wonder now that she was close enough to slip a knife in between his ribs if she chose to. Allowing her to lead him in the direction he guessed was toward the museum, Dean asked, "So uh is Sam your boyfriend or something? And what happened that made you decide you needed a metal bar to defend yourself with?" It struck him as almost funny considering the fact she knew the Doctor and that dude was such a pacifist that Dean figured he'd have talked anyone out of using weapons to defend themselves by now.
