So I died. Went to heaven and was approached by Zachariah who claimed they needed my help to stop the devil. They also offered to reunite me with my mom if I agreed. Obviously I agreed.
I was resurrected and found by Castiel, brought to Sam and Dean, decided I didn't want to bond, was taken by Angel's, and found out it was a trap and I was being used to get to Dean. They came for me but I got separated from them while we were escaping and became Mike's vessel.
The rest is kind of a blur until we wound up trapped in hell.
