Sam went flying over the cuckoo's nest on Supernatural last week.
How will this CW hit follow up yet another heart-pounding episode? Via "The Girl Next Door," which brings Jewel Staite's Amy into the picture. Who is this demon? She's the same being Sam came across as a child, and she's been killing thugs and feasting on their brains when Dean finds her this Friday.
Get an early look at the upcoming installment below, courtesy of its official CW preview:
