Dean's about to ask how far it is to the next rest stop that Cas scouted out, when the angel throws an arm out in front of him.
"Hey-" Dean starts, but is silenced by a pointed look from Cas.
Cas jerks his head, gesturing towards a shape on the ground ahead of them. As Dean's trying to make out what it is, Cas leans towards him, until his lips brush against Dean's ear.
"We don't want to wake it," he whispers.
Dean realizes what he's looking at. Fingers the size of logs. The curve of a palm, large enough to hold both him and Cas.
He doesn't mind taking the long way around.
