Carver also teased that there would be some returning characters — one episode will team Sheriff Mills with Sheriff Donna Hanscum from the episode “The Purge,” and the show will be doing its own version of The Heat.
"There was a part of me that was a little concerned that Misha would try to do something, but I thought, nah, there’s no way he’s that stupid," Ackles says of pranks while he was directing. "I’ll getcha. Just because you’re not directing doesn’t mean you can’t be screwed over," Collins promises.
"We’ve been describing the [200th] episode as ‘musical-ish.’ it’s very much what we consider to be a love-letter to the fans." says Carver. "Technically in the season opener, there’s singing and music involved as well," says Ackles. "And a little rump shaking," adds Carver. "Apparently Demon Dean likes to karaoke," Ackles says.
