Dean was too tired to drive and there is no way in hell he was gonna let you drive his Baby. There wasn’t a motel anywhere near by. So last resort is sleeping in the Impala. It wouldn’t be the first time and definitely not the last. The vampire case they just worked on was stressful enough already and Dean needed his four hours of sleep.

Dean lays in the front seat as you lay in the back “Doing okay back there, Sweetheart? Do you need my jacket for a blanket?” He asks. His tone is tired but he still cares enough to make sure you feel okay.
