"Oh, right..." He looked over his shoulder absently. Zipping Dean up wasn't exactly the greatest alternative, but... yeah, necessary. He gave a nod.

"I should try and get some more sleep, if I'll be driving some of the way in, I guess." Hopefully his dreams stayed in the realm of innocent... and not pornographic or horrifying... which was actually the least appealing of all the options. It was actually kind of embarrassing to wake up screaming from a nightmare with Dean right there...

But on the plus side, sleep might ease up on any remaining tension anyway. He leaned back in his seat a little, tipping his head against the door.
