Dean is keeping more than just Sam's angel possession a secret on Supernatural.

When Dean (Jensen Ackles) gets a ghost hunting related call from an old friend named Sonny (Blake Gibbons), the Winchester brothers travel to a home for delinquent boys. Unbeknownst to Sam (Jared Padalecki), the home was briefly visited by a teenage Dean after he was caught steeling food.

As the hunters attempt to deal with a murderous ghost, Dean flashes back to his past and Sam tries to persuade him to fill him in on the story.

"There will be another early episode where we flash back to the young boys - we're going to see a part of Dean and a life experience for Dean that both the audience and Sam never really suspected," said executive producer Jeremy Carver, according to Give Me My Remote. "So we're going to uncover a part of Dean we didn't realize existed. It'll be a very emotional episode for Dean."

New photos from Spoiler TV, which can be seen above, give fans a first look at what they can expect to see in the upcoming flashbacks. A teenage Dean, probably around 14 or 15 years old, can be seen with Sonny in various scenes, while a young Sam (most likely not Colin Ford, who previously played a young version of Sam) can be seen hanging out of the Impala's back window.

The teenaged Dean is also pictured with a girl who, in one photo, it appears he is going to kiss. This could be Robin, a woman who is now in her 30s and was in some sort of relationship with Dean nearly 20 years ago, according to E!. Expect to see Dean look her up now that he is back in town.

"I know it isn't the sexy pitch, but we're really digging into our characters here, and we're hopefully rounding them out in a way that folks haven't even seen yet, and that, for me, having been on the show several years, it's a real fun place to be," Carver told Ksite TV.
