It is hot enough to do without one, although really they should get the hell out of this motel and drive. Cas doesn't think either he or Dean will be able to make it very far before stopping again.

Cas emerges from the bathroom, pulling a shirt on over his head, and sees Dean staring at his phone. He can guess why; he needs to call Sam and Bobby and inform them, but more than anything he thinks Dean needs to talk to his father figure and little brother.

Cas dials Bobby's number and tosses the phone to Dean as it begins to dial.
