Aliens. It's a word that Sam and Dean Winchester will not tolerate on Supernatural.

'Supernatural' Writer Teases 'About A Boy', Dylan Everett's Return As Teenage Dean

Unfortunately for the brothers, what appears to be a mini version of the Rapture will have witnesses spewing alien abduction theories in "About a Boy."

With a flash of light, adults are vanishing into thin air, leaving nothing behind but their clothes. Clearly they aren't heading to the mother ship for experimentation or being whisked away to the fairy realm, but their fate is not much better. Hansel, of Hansel and Gretel fame, will be busy de-ageing his unfortunate targets, hunting down new victims for the witch (see video below).

Sam To Get A Visitor From His Past On 'Supernatural', Who Will It Be?

Before the Winchester bros. can figure out Hansel's master plan, however, Dean (Jensen Ackles) will fall into his trap. Suddenly reliving his teenage years, young Dean (Dylan Everett) will have to team up with his "little" brother in order to regain his 36-year-old form.

Dean won't be truly horrified, however, until he realizes his teenage self will have to let Sam drive Baby. Scroll through the photos above to see what's in store for the hunters when they take on Hansel and the witch.

Penned by Adam Glass and directed by Serge Ladouceur "About a Boy" will air on Feb. 3.
