Meanwhile, showrunner David Amann said that the episode will be a joy ride and viewers can expect a lot of fun.

"It's an incredibly fun and charming episode and I think a good follow-up to episode six in that regard," Amann told Entertainment Weekly.

A promo video of the upcoming episode shows both Rick and his detective wife unbuttoning their shirts, but their moment of passion is interrupted by an uninvited guest, a snake.

The official synopsis of episode 7 'Once Upon A Time In The West' reads: "When Castle and Beckett learn that a murder victim may have been poisoned at an Old West-style resort, they visit the resort posing as newlyweds to uncover the truth."
