CASTLE: Seamus Dever Previews Ryan’s Quest to Be Castle’s Best Man, and the Upcoming Season Finale

As CASTLE’s Castle and Beckett get closer to their wedding day, the final preparations are being made. And in this Monday’s new episode, “Law & Boarder,” Ryan and Esposito have a particular task in mind they want to claim ownership of.

“Esposito and Ryan are both vying to be best man for Castle’s wedding,” CASTLE star Seamus Dever (Ryan) laughed. “There’s this comedy of errors where Castle thinks we’re talking about something different, and he doesn’t catch on that they’re sucking up to him and trying to be his best buddy in like a really cloying, annoying way. We’re suddenly just on him, completely, and really competing with one another. So that’s a lot of fun. It’s always fun when Jon [Huertas (Esposito)] and I have to compete about something. We get digs in, and we give each other looks, and there’s lots of things at stake for Ryan and Esposito in that episode.”

And while Castle may be oblivious to what’s going on, Ryan and Esposito’s antics do catch the attention of Beckett.

“Oh, she’s aware of it,” Dever said. “And Stana [Katic (Beckett)] did a great job of catching on very early that we’re acting different all of a sudden. It’s mostly [her] watching us running around chasing our tails. ”

But whether one — or neither — of the men lands the spot of Castle’s best man, Dever hinted there might be trouble ahead before Castle and Beckett an get the chance to exchange vows.

“Beckett and Castle are heading to the altar, but do we expect everything to go off without a hitch?” Dever teased. “No. Come on. It’s CASTLE. There are some obstacles throw in their way, and I will say at the very end of the season, the audience will be challenged, and eager to find out how we pick up from here comes September.”

Whatever trouble the duo finds themselves in, Dever acknowledged that Ryan won’t be around to witness much of it.

“Ryan’s completely removed from the storyline [with guest star Eddie McClintock, who plays someone from Beckett’s past],” Dever said. “You’re not going to see Ryan very much in the last two episodes.”
