Season Six Episode Specifics
Dean will be getting wings. The source said the creative team was eager to find new ways to torture and push this character to his
limits, and they hope to do this as realistically as possible: What about all the molting? How will he fit in the Impala? Can he fly? Will Sam feel differently about his brother? How does Castiel feel about this?
Castiel will be getting into more fights this season. The make-up department has been given instructions to make sure they put most of the blood so it trickles down Misha Collins' nose just so.
Mary and John will be appearing as ghosts that only Dean can see and hear. Tensions rise as they try to give Dean advice, and there's a hilarious, heart-warming moment in the third episode where John starts lecturing Dean from the back seat on how to drive properly.
Becky the fangirl is returning for one episode set at another fan convention. A fight breaks out between Sam/Dean shippers and
Dean/Castiel shippers. Our source says the production team tried to keep it tasteful, but there might be some hair-pulling and
There are plans for a body-swap episode. "No, really, this time!" stated the unnamed source. Sam and Dean will be swapping bodies.
Gabriel/The Trickster will be causing some hijinks. There might be ponies involved.
Finally, our source said that per an internal memo from Sera Gamble, who takes over from Eric Kripke as showrunner next season, there is a new directive to have Sam be naked and crying as much as possible.
