We’ve seen our fair share of weird drama on the hit CW series “Supernatural.” And despite all the talking Teddy Bears and maniacal clowns who made their debut on the long-running TV show, there’s a new character introduced in episode 19, “Alex Annie Alexis Ann,” that has us sporting some serious goose bumps.

“Annie Jones. Reported abducted in 2006,” Sheriff Mills tells the Winchester boys in a leaked sneak-peak preview of episode 19. The officer hands Dean and Sam a “Missing Child” flyer from years back. On the paper is a picture of an adorable little girl.

“Raised by an elderly grandparent. No living kin,” she added. The trailer than cuts to a scene of the group looking through the police station window of a grown woman with the same colored hair as the child in the photo. It’s safe to assume Annie Jones has been finally found.

“You think the vamps are the ones that took her?” Sheriff Mills questioned.

“Eight years is a long time for a human to live with vampires without getting killed or turned,” Dean responded.

“You’re the experts,” Mills said. “But there was something familiar about the way this vamp talked to her."

“Jodie’s right,” Sam chimed in. “And she had scars on her neck. Feeding scars. They were layered. As if they’ve been built on for years.”

“So, she’s a blood slave,” Dean attempted to solve the puzzle. The sheriff looked confused. “We’ve seen before Vampires keeping people as pets—human feed bags. Sometimes as slaves…”

“…Stay loyal to their captors,” Sam finished his brother’s sentence.

“So, this girls not talking because she has a case of what -- vampiric Stockholm syndrome?” Sheriff Mills questioned.

Stockholm syndrome is a psychological phenomenon in which hostages express a sort of empathy toward their captors. According to studies, it’s also seen as a form of traumatic bonding after “one person intermittently harasses, beats, threatens, abuses or intimidates the other.”

A famous case of this syndrome includes Patty Hearst, a rich heiress who was kidnapped by the American terrorist group Symbionese Liberation Army in 1974. Hearst was 19-years-old at the time she was taken from her apartment in California and eventually became to sympathize with her captors. Three months after getting kidnapped, Hearst was photographed robbing the Sunset District branch of the Hibernia Bank in San Francisco.

So, do the Winchester bros think Annie has the same syndrome as Hearst?

“She’s protecting the nest,” Dean replies.
