The description for episode 20.
“Don’t Call Me Shurley” —

ROB BENEDICT RETURNS – Amara (guest star Emily Swallows) 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. Meanwhile, Chuck (Rob Benedict) returns with an interesting proposal. Robert Singer directed the episode written by Robbie Thompson (#1120). Original airdate 5/4/2016.

Chuck returns! Will we get confirmation on if he is or is not God? Amara releases another black virus. Will the cure for this be burning it out with Holy Oil? Or is it too strong for that?
What do you think? Are you glad to see Chuck return? Is the Amara storyline actually going somewhere? Let us know in the comments or in the discussion thread for episode 20.
