"Castle" season 7, episode 6 spoilers reveal that confusion will arise when Nathan Fillion's Rick finds himself being unrecognized by anybody in the precinct, including Beckett. The upcoming episode will also reportedly see Caskett's wedding finally taking place.

According to the "Castle" season 7, episode 6 spoilers from Cartermatt, the wedding will be some sort of "last-minute" decision for Rick and Beckett.

And it will be explained in the episode what prompted Rick to immediately push through with the wedding despite their earlier agreement that they don't need to rush off marriage particularly with what happened in last season's finale.

Executive producer David Amman dished "Castle" season 7, episode 6 spoilers toTVGuide as he said that this is where the alternate reality that they promised earlier will be shown.

In the episode, Rick Castle will have a "Twilight Zone-like" experience where he's not known in the precinct. It's not clear whether this is just Rick's dream but eventually he snaps out of it to profess his love for Beckett and asking her to marry him.

Amman also said that fans won't be treated with the same kind of wedding at last season's finale.

"We came very close to doing the other version of the big wedding... and all the hoopla that's associated with that, and we knew that we didn't want to do quite the same thing," he said about Nathan Fillion's and Stana Katic's wedding.

"[Beckett] doesn't necessarily know quite what has driven him to this point, but she's emotionally right there with him. It's a wonderful, wonderful moment, and we hope the fans share that view," the executive producer added about the "Castle" season 7 spoilers.

The wedding episode will immediately be followed by the Honeymoon episode.

"With its dude-ranch theme, this is apparently going to be the honeymoon episode for the two characters, but nothing is going to go according to plan. At one point, it looks like Stana Katic's character accidentally shoots him!" said Cartermatt.
