Adam is back! As revealed in September, Supernatural alum Jake Abel will return to the series for its final season. Now, he has clarified he will play both the archangel Michael and the Winchesters' long-lost brother in Season 15.

"I play both, and our hope was to create two distinct characters," Abel told Entertainment Weekly. "There are things that happen that I don’t want to give away that there was an importance for me to create two different characters and be able to transition between them fluently, which was an awesome challenge. There’s some stuff in the scene that surprised Sam and Dean, so I have a feeling it will surprise audiences as well."

What's more, this may not be the last we see of them on the show. "I don’t think it’s over. I think it’s leading to something spectacular, or at least I hope so. When I was on set with Jared [Padalecki] and Jensen [Ackles] and they’d ask me, 'Do you have any more episodes?' I was like, 'I don’t know, I’m just here right now enjoying this.' They both said, 'I’d be surprised if you didn’t have more because what you’re doing in this episode is setting up everything,'" he explained.

"What Adam and Michael are doing in this episode is setting up all the stuff that’s about to happen. So that’s my hope. There’s been some talk about what might happen in the future, so I think it could be going somewhere and I do hope it is explosive. But for now it definitely feels like a setup," he added.

Adam is Sam and Dean's half-brother. He was born to Kate Milligan, a nurse who ran into John Winchester after a hunt left him injured. In Season 4, a ghoul disguised as Adam reached out to John in an effort to trap and kill him. Since John had died, Sam and Dean answered the call. Neither Adam nor Sam and Dean were aware the other existed. By the time the Winchesters realized who Adam was, it was too late; he had already been killed by the ghoul.

In Season 5, Adam was returned to life to play a pinnacle role. The angels convinced Adam to become the vessel for Michael, who was destined to defeat Lucifer and usher in the end of days. When Sam threw himself into Lucifer's cage, disrupting the prophecy, Michael followed Lucifer back to hell. This trapped both Michael and Adam in Lucifer's cage, where they stayed -- until now.

Airing Thursdays at 8 p.m. ET/PT on The CW, the final season of Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert.
