Sam has a reunion with his former girlfriend, Amy, in a new sneak peek for the next episode of "Supernatural", but it is not a sweet encounter. In fact, the younger Winchester is seen stalking her in the woods while the girl herself is following another man who may be her next prey. The clip ends as Sam surprises her from behind and points a knife on her.
Played by former "Firefly" actress Jewel Staite, Amy is Sam's high school sweetheart who has been killing low-life thugs and taking their brains for dinner. In the upcoming episode titled "The Girl Next Door", Sam disappears to follow a lead on the case with clues that are identical to a case he solved as a kid, making Dean furious.
The October 7 outing is directed by Jensen Ackles. Executive producer Sera Gamble recently shared that the upcoming episode will take viewers to know better about the Leviathans, which previously took over Castiel's body, but will not reveal their boss yet. On whether or not Misha Collins will return after his character Cas was stewed into the water, she teased, "It has always been our intention to bring back Misha in some form."
