Well, it’s official: The Mark of Cain is turning Dean into what Supernatural would call, well, a dick.

In a new promo for the mid-season premiere, first acquired by Variety, Sam finds himself doing everything he can to try to stop Dean from going dark, including letting Metatron out of jail and bringing him back to the bunker.

However, Metatron isn’t the only one getting in on the fight against the Mark. The promo also gives us a first look at the return of fan-favorite Charlie, though it doesn’t seem Dean is too happy to see her. Yes, he did just punch her in the face.

Supernatural returns Tuesday, Jan. 20 at 9 p.m. on The CW.
