"Well, that’s a wrap on the first episode of the final season," Ackles wrote. "Directing was intense...as you can clearly see. Here is my transformation back to good ol #DeanWinchester. Feels good. #Spn15 #spnfamily"

"I feel like Sam and Dean find some version of peace," Padalecki said regarding Season 15 in July. "Whether or not that’s alive or dead, or if Amara possesses me or whatever the situation is, I feel like they find more peace than when the season starts."

"My reaction was more like, ‘OK, OK.’ I struggled with it for about a week or so, and then I realized I’m too invested, I’m too emotional. I’m too close to this character. To see anything with finality on it, it’s just hard to digest," Ackles added.

Returning Thursday, October 10 at 8 p.m. ET/PT on The CW for its final season, Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert.
