....Right. Dean clears his throat again, for no real reason. "Yeah. Okay. I guess not."

Those are as many feelings as Dean can manage for now, so he just keeps driving in silence. Unfortunately for Cas, they're really in the middle of nowhere, so there isn't even a gas station for Dean to stop at. They're trapped in the car together for the moment and Dean hasn't even seen fit to turn on the radio. Uncomfortable silences all the way!
