Dean was killed not to long ago by a hellhound but was brought back without his brother Sams or Bobby his older father figure friends knowledge.
Dean was brought back from hell by a angel named Castiel. he crawled out of the dirt, where he had a hunters funeral.. a few hours later Dean was walking the main road in a tight shirt dirt on him and his jeans.
Dean put his thumb up hoping someone would give him a ride when a nice old car pulled up next to him a pretty girl rolled down the windows who he didn’t know, “where you heading?”
He told you Bobbys address and you immediately perked up, “Bobby singer?”
he raised an eyebrow confused by you knowing who Bobby was off his address, “you know him?”
you nodded and unlocked the car door immediately trusting him since it was a friend of Bobbys, “we hunt together sometimes”
he got in with a hint of suprise and confusion, “your a hunter?”
