We're almost at the end of the season. Here's the synopsis for the penultimate episode of season 11.

“We Happy Few”

THE FINAL COUNTDOWN – Sam (Jared Padalecki) and Dean (Jensen Ackles) face their biggest challenge yet. Rowena (Ruth Connell) makes her move. John Badham directed the episode written by Robert Berens (#1122). Original airdate 5/18/2016.
The title has a couple of possible references. The quote is originally from Shakespeare the Saint Crispin's Day Speech from Henry V, as Henry encourages his troops to face battle. The other possible reference is to a video game We Happy Few. Do you think either of these references give us a clue into this episode?

What will be their biggest challenge? What is Rowena planning? We don't have a lot of information here. Give us your thoughts in the comments or in the discussion thread for episode 22.
