The time has finally come for wedding bells on Castle and there is only one final wacky road bump before Castle and Beckett say “I Do!” Check out the synopsis and episode stills below.

Castle fans can finally rejoice because the longest wait is over. At the end of this episode Castle and Beckett will officially be man and wife. Of course it won’t be any easy walk down the aisle. Read on for more details.

The official synopsis for Castle season 7, episode 6, “The Time of Our Lives,” is:

“A murder investigation launches Castle into what seems to be an alternate universe where he’s never met Kate Beckett. Castle has to convince Beckett, Esposito and Ryan — now complete strangers — to let him participate in their investigation so he can find his way back to his own world. This inspires Castle and Beckett to finally take a trip to the altar.”

The guest cast includes Julian Scott Urena as Renzo Conrad, David Francis Harris as Mathias Gensler, Jeffrey Nordling as Marcus Lark, Scott Paulin as Jim Beckett.

It wouldn’t be Castle without a wacky case to make Castle realize what is important. Here’s hoping there are plenty of callbacks to previous Caskett moments to make up for the previously aborted wedding at the end of season 6.

There aren’t too many clues to the actual wedding in the released photos. One difference is Alexis, check out that hair! What other changes are in store for the hour before we return to our Castle reality. Check out the images below.
