You probably know the answer to the question posed in this headline, if you’ve seen the images The CW has released from the October 8 season premiere of Supernatural, which is called “I Think I’m Gonna Like It Here.”
If not, the official description from The CW probably gives it away:
FALLEN ANGELS — Dean (Jensen Ackles) is frantic after Sam (Jared Padalecki) collapses and the doctor tells Dean his brother won’t make it. Desperate, Dean sends out an all points bulletin via prayer to every angel in the area, asking them to help his brother. In exchange, Dean will owe that angel a favor. Numerous angry angels race to find and kill Dean, but one, Ezekiel (guest star Tahmoh Penikett), gets to him first. Meanwhile, Sam fights for his life and must face some familiar demons to do so. Castiel (Misha Collins) struggles to survive without powers. John Showalter directed the episode written by Jeremy Carver (#902).
Here are some those promotional images, by the way, in case you missed them earlier:
