While it had taken some time for Dean to get the bus started, now there seemed to be little trouble with getting it moving. It was a far cry from the Impala -- even Castiel knew that -- but it seemed like so long as it had a steering wheel and traveled on land, Dean knew how to drive it.
Despite Dean's suggestion, however, Castiel wasn't willing to go sit down, even though there were more than enough seats to choose from. While he doubted that most monsters would be able to get to them when they were in the bus, that didn't mean he was comfortable enough to not keep some sort of look out. Figuring that Dean would need to keep his eye on the road ahead (it wasn't well-lit, after all, and they were surrounded by a thick forest on either side), Castiel took on the task of looking through the windshield at the area around them. He remained standing, slightly to the side from where Dean was sitting, and grabbed for a bar overhead to keep his balance as the bus passed over unsteady ground. If something tried to ambush them, he wanted to be aware of it.
None of this felt particularly safe, but that was almost comfortable for someone like Castiel. What he and Dean were doing now -- it reminded him of past times, of times that Dean had not yet experienced.
"You know the way, correct? There should only be one road." Still, if they got turned around or took a wrong turn, it could turn very bad for them.
