Castle

Just hours after wrapping shooting on the shocking Season 3 finale of Castle, Seamus Dever, who plays Kevin Ryan on the ABC hit, told Wetpaint all about it. In Part 1 of our exclusive interview, Dever — still bruised and exhausted from the epic shoot — explains why the finale is like the grimmest part of the Star Wars franchise, hints at trouble brewing between Ryan and Esposito, and tells us just how Castle and Beckett should get together… if they ever do!

Wetpaint: What can you tell us about the finale?

Seamus Dever: It's big. It's dark. I've been calling it our Empire Strikes Back episode because it's dark. I mean, The Empire Strikes Back is my favorite movie of all of them for that reason. It was realistic. There's not much hope that comes out of the season finale.

I think it's going to probably really excite a lot of people and they'll think, "Oh, what a great episode!" And other people are going to go, "No! No!" And they're probably going to be screaming at their television. [Laughs] It's going to have a reaction.

And I hope people like it because we really, really worked very hard on it. I've got the bruises and scrapes and blood to show for it. I really hope that the audience does respond to it, and that it propels them to come back with us in the fall.

Do you relate to Ryan at all?

Absolutely. I relate to the idea of someone being the young guy on the team. There's something to learn from everybody. I like his sense of smartass-ness. That's just like me in real life. I think he's a lot closer to me than a lot of the characters I've played in my life.

Jon Huertas (Javier Esposito) told us he wanted to see the friendship between Ryan and Esposito tested? How would you feel about that?

People have really responded to our characters and they want more of us out there. I'd like it to be a real relationship that we have. People have ups and downs and people have fights and I think you're going to see some of that in the season finale. We were filming very late [Wednesday] night — something towards that point. So Jon's right. We want to see us getting upset with each other and then making up. You know, having girlfriends and being on dates, just what happens in a real partnership. People put things up between us. I think we'd like to see that fleshed out a lot more and conflict is part of that.

Should Castle and Beckett get together?

I think they should. [Laughing] Usually in an interview that's the first thing that somebody asks me, so I want it to just happen so we can all just move on. I think the audience will go with us because I think the show at its core is not just about, "Oh are they gonna finally do it?" And then you hear everything about "The Moonlighting Curse," which is B.S. because people forget there was a writers' strike during the middle of that whole thing so Moonlighting went away and lost momentum. There were other circumstances. The curse is crap. There's shows like Bones — they got together, right?

Getting together doesn't mean happily ever after. I think people expect all of their differences of personality to be just completely solved. I know in my relationship it's not true. We fight, we make up, we learn a little more about each other. And I think that's probably what's going to happen with Castle and Beckett, is that they get together, and then they fight, they break up, they come back together, they fight… And there might be an endless cycle, just sort of like there is in a lot of the tumultuous relationships out there.

If they get together, I'd like to see it raise certain questions about what happens when they put each other in harm's way, which tends to happen to them. It will be interesting to see what will happen next season because I have no idea where we go from here. You'll understand that statement when you see the season finale. Where do were go now?

Who is your dream guest star?

A lot of my dream guest stars are people that are my friends that I'd like to come on the show and work with again. People that I've done plays with and stuff like that. This is a small one, but there's an actor named Colm Feore on The Borgias. I'd love for him to come on the show and play my dad some day. All of my favorite people are like that, are people like Robert Duvall. People who are solid actors. You want to work with them. I don't know if they'd ever do TV but people like that I'd love to have on the show.
