Supernatural is currently shooting for a particularly "odd" season 10 episode.

Filming as episode 1009 (airing order unconfirmed), the untitled episode may be shaping up to be one of the series' more bizarre episodes. It looks like fans could have another "Clap Your Hands If You Believe" on their hands.

"Yep! It's an "odd" episode!" teased director Guy Norman Bee ("Stairway to Heaven," "Devil May Care"). "That's a good thing! #1009."

The upcoming episode will also include a shocking twist in the final moments.

"This episode has a huge twist at the end!" tweeted S.E. Hinton, a Supernatural fan and writer of The Outsiders, after a recent set visit.

New set photos (see above) reveal that the Winchester brother won't be flying solo on the case of the week. Instead, Castiel (Misha Collins) and his trench coat will come along for the ride. Whether or not he will be up for a fight, however, depends on the state of his failing grace.
