Supernatural is going big for its fifteenth and final season. According to star Misha Collins, who plays Castiel, the Season 15 premiere will channel some of the biggest fantasy shows in recent memory.
"It's like The Walking Dead meets [Game of Thrones'] White Walkers out there," Collins told TVInsider. "So we have to make a deal with the devil to help us. It's a difficult pill for Cass to swallow."
The report clarified that Castiel and the Winchesters don't team up with the actual Devil (been there, done that). However, Collins teased this Faustian bargain won't sit well with the angel, especially following his recent failure to save Jack from himself -- and from God: "For Cass to have been on watch when Jack died is a crushing blow to him."
In the Season 14 finale, Sam and Dean Winchester came to the horrifying realization that the course of their lives had been personally steered by God's whim; every hardship, every tragedy had been crafted by God for his own entertainment. When they pushed back, God retaliated in kind, launching what may well be the end of everything. Heading into Season 15, the Winchesters will have to rail against the Creator himself to find peace at last.
Returning Thursday, Oct. 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.
