No. I saw a really good picture of his arm. It looks almost like the locking thing that Meg put on Sam’s arm when she possessed him way back in Born Under a Bad Sign. The handprint has been gone for a long time but that was on the opposite arm anyway. It looks to me like Michael marked him? Or maybe locked himself in there?? Idk.
Okay, honest opinion: Does Dean still have the Cas handprint from season 4? Does Sam have one from season 6? Considering the Winchesters have died and been resurrected multiple times, would they still have them or not? (Personally, though I’ll take it if it’s canon, I want the mark to be gone. I don’t have the pairing but any type of fodder makes that side of the fandom unbearable.)
