Castle creator Andrew Marlowe spoiled some of the anticipated story for season 5 of the ABC hit crime drama. Marlowe teases Beckett's new beginnings, the many hurdles that Caskett will face next season plus dish on Beckett and Esposito's insubordinate actions with Captain Gates.
Ultimately, you get to a fork in the road. If we kept them apart any longer, say another season — after what Castle had put on the table at the end of last season — in my mind, that would have been the death of the series. Then, we would have just been being artificial. They would have become brother and sister, and then we're just ignoring everything that had happened. There comes a point where you have to confront it. ... We wanted to get the point where we resolved it and made a promise for next season that these two are going to have to be dealing with their feelings for one another. I think we need to get to the other side of the storytelling. I think we've played the interruptions as much as we possibly can. And I think we're really interested to see what's going to happen with these two. What does that relationship look like? This is going to allow us to reembrace some of the fun, because relationships are tricky things and they don't always go the way you want them to. [Seeing them] figuring out their rhythms with one another is going to be fun for the audience to watch. In no way do we think this is going to end the fun and the tension between Castle and Beckett because the question is now going to become: Where does this relationship go and how does it affect their ability to work together? We do put the relationship under threat right away with Maddox's threat at the end of the episode. [Beyond that,] I have a good ballpark sense of where we're going. And I'm not going to advertise it too much because that's the fun of the ride. You don't want to show everybody exactly what the rises and falls of the roller coaster are when they get on it. You want them to be surprised at the twists and turns. Sleeping together is a great hallmark, but to get to the promised land of a happy ending, there's a long way for these guys to go. Unbeknownst to Beckett, her life is still very much in danger, and that's something we're going to be picking up the thread on when we come back next season. We're looking to get Beckett beyond some of that stuff to the point where she can rediscover who she is and [she and Castle] can deal with this decision they have made.
Beckett and Esposito [Jon Huertas] have crossed a line. So, what does that mean for them as cops? Gates [Penny Johnson Jerald] ends up being much more of a significant obstacle in the first couple of episodes next season. [With] Beckett and Castle getting together, we felt it was time to challenge some of the other relationships so we'd have somewhere to go with the storytelling. Ryan has to make a choice that ends up with Esposito feeling like he's been betrayed. The two of them are definitely on the outs.
