Will They or Won't They? Nathan Fillion and Stana Katic Talk Castle Romance

Nathan Fillion and Stana Katic spill scoop about what to expect from ABC's Castle during sweeps

News Flash: People like, like Castle.

Correction: People like, love Castle.

After mentioning that we'd be visiting the set for scoop, you harassed asked us via Twitter/email for the goods and bless you for it, 'cause we have some serious business to discuss, friends: Could the writers of Castle be trying to pull Beckett (Stana Katic) and Castle (Nathan Fillion) apart to keep things fresh? Here's what we learned:

Our crime-solving heroes might be spending some serious time apart over the next batch of episodes.

Nathan reveals that the dynamic between Castle's two main characters has changed this season, thanks to the addition of a third and fourth party. He says, "I think we're going to see a little more of Beckett on her own, with this new beau perhaps, and Castle on his own with his ex- wife, who's now, again, his girlfriend. They've been very good about exploring this will-they-or-won't-they relationship, and this year a new twist on it is that they are both in separate but viable relationships. And it's not, 'Oh my god, it's so obvious that person's so wrong for them, but real, honest, great people who are deserving of love and trust in these relationships.' "

In case you haven't heard about Beckett's fella, Stana tells us, "In one of the upcoming episodes, Beckett is dating a character named Josh who's played by Victor Webster. Victor is this tall, gorgeous Canadian who's guested on the show, and apparently he's a bike-riding bad boy who's also a cardiac surgeon. So hopefully it'll bring some fun competition and romantic tension to the set and to the show." (Editor's note: McDreamy + Jax = McSeriousCompetitionForCastle.)

So what's Stana's take on the sexual tension between Castle and Beckett? Do they have what it takes for the long term, or could they really be torn asunder by the likes of Victor's Josh? Stana says, "I always feel naive saying that I think that characters can get together and still have a spicy relationship. I don't mind if they get together. I think that they fit and fill each other's lives really well. He's her perfect opposite, she's his perfect opposite, and in some ways they are each other's perfect parallel, because they are both really passionate about the same thing, which is solving crimes. Everyone's always [talking about] this Moonlighting curse, but then I'm like you know there's [also] Mr. and Mrs. Smith [as a counterexample], and everything was fine with them, and they were superspicy."

Oh, and speaking of romance, there's more than just Castle-Beckett happening on Castle. We hear that things might start getting serious for Lanie (Tamala Jones) and Esposito (Jon Huertas) around episode 11.
