The offer took him by surprise. Bucky couldn't even hide his reaction, his head turning toward her in question. Vampires weren't exactly quiet about their dislike for his kind (and the dislike was generally mutual), and he'd figured the last thing she'd want was to let him into her personal space.

He almost asked if she wasn't worried about having to deep clean to get out the dog smell, but he didn't want to play into that. Besides, he didn't want to repay an attempt at kindness with snapping.

After a slight pause, he turns off the engine. "You sure you're okay with that?" he asked instead, giving her the chance to back out.
