Quitting hunting and moving in with an ex-one-night-stand, Lisa, Dean begins to move into a normal life but is thrust back into hunting when attacked by a Djinn and mysteriously saved by Sam. Shocked to learn of his brother and maternal grandfather's resurrections, Dean is placed even more on edge when Sam acts cold, ruthlessly and lets Dean get temporarily turned into a vampire. This is mostly shocking because out of the brothers, Sam has always been the gentler of the two.
