'Supernatural' Season 11: Chuck Has A 'Proposal' For The Winchesters, Episode 20 Plot Revealed [VIDEO]

Why Will Chuck Return To 'Supernatural'? 'Don't Call Me Shurley' Plot Revealed!

Welcome back, Chuck. The Supernatural family is happy to have you.

Virtually unseen since the apocalypse, the prophet/writer/potential deity will make his return "Don't Call Me Shurley." Set to air on May 4, episode 20 will put Rob Benedict's character in touch with the Winchesters as Amara (Emily Swallow) ups her game.

"Amara unleashes a dark fog on a small town, causing everyone to go mad. Dean (Jensen Ackles) and Sam (Jared Padalecki) realize this is a stronger version of the original black vein virus Amara previously unleashed. They team up with the sheriff to protect the town but their old remedy no longer works," The CW teased. "Meanwhile, Chuck returns with an interesting proposal."

Will Chuck reveal himself as the God squads big kahuna, or will Castiel's (Misha Collins) dad continue to be a no show? Padalecki couldn't confirm or deny the rumors while attending a recent convention, but the actor did tide fans over with a tantalizing tidbit.

"There have been few times in my life as Sam Winchester that I've read the script and had tears well in my eyes and the sensation like when you get the shivers and your blood vessels dilate and you get goosebumps...Twenty is awesome," Padalecki teased at Creation Entertainment's Salute to Supernatural in Nashville. "Twenty is awesome, awesome, awesome, awesome."

Set photos have confirmed Chuck's continued presence through episodes 22 and 23.
