Next week's episode of Supernatural Season 10 is one of the most anticipated installments of the season, as Dean (Jensen Ackles) goes back to his younger self.

The official synopsis of Supernatural Season 10 Episode 12 reads:

"Looking to get Dean out of the bunker, Sam (Jared Padalecki) finds a case for him and Dean to investigate – people are disappearing into thin air with only their clothes left behind. Sam and Dean suspect fairies or angels, but the truth turns out to be much more shocking – Hansel (guest star Mark Acheson), from Hansel and Gretel lore, is kidnapping people and turning them into their younger selves to placate the evil witch (guest star Lesley Nicol). Unfortunately, Dean finds this information out the hard way after he becomes Hansel's next victim and reverts to his 14 year old self."

The upcoming episode, titled 'About a Boy,' it will show the Winchester brothers working together to investigate a special case to prevent people from disappearing mysteriously.

Their initial suspicion that angels or fairies are the ones responsible for all the suspicious vanishing of random people proved to be wrong, after evidences showed that an individual named Hansel was the one who abducts the unsuspecting people to turn them into teenagers to please the evil witch.

Can Dean still return to his old self after he got the age-reverting spell from Hansel?

Guest star Lesley Nicol, the actress who portrayed the role of Mrs. Patmore in the hit BBC series Downton Abbey, will be the evil queen in the upcoming episode of Supernatural Season 10. Mark Acheson, on the other hand, is a season voice and professional actor whose latest works include Watchmen and The Trial of the Incredible Hulk.
