The future of Beckett and Castle’s relationship is in danger.

Fresh off Castle’s renewal news, season five wraps up with the ABC procedural, starring Nathan Fillion and Stana Katic, forcing its two lead characters to make a big decision. Beckett is faced with a job offer she is seriously mulling, which would put her in Washington D.C. and threatens her romantic future with Castle.

“It’s bittersweet,” actress Molly Quinn, who plays Castle’s daughter Alexis, tells The Hollywood Reporter of Monday’s season finale. “It gets to a point where Castle wants one thing and Beckett wants another, and if they can they work it out or not.”

In a chat with THR, Quinn discusses Alexis’ newfound “daredevil” streak, how her near-death experience has changed the character and what the future holds for the Castle-Beckett romance.

The Hollywood Reporter: What should we expect for Alexis in the season finale?

Molly Quinn: Alexis is trying to convince her dad that it is OK for her to take a trip to Costa Rica and her dad, of course, is very uncomfortable with that considering what happened to her earlier this season with her being kidnapped and everything. Alexis is trying to reassert her independence because after that whole experience, her dad is much more overprotective. I mean, Alexis was still shocked — she would be after that traumatic situation — but now she’s like, “Hmm, this isn’t good. I can’t let him think that we’re reverting back to being 14. I’m 19, going on 20, I need to take this trip because I can’t let my fears conquer me.”

The answer we’ve been waiting for is coming early:

ABC has officially renewed Castle for a sixth season!

I’ll have more on the renewal and news as it comes out, congratulations to the cast and crew on another amazing year and here’s to many more!

The cast members of “Castle” have a big reason to celebrate.

The ABC comedy drama’s cast, which includes stars Nathon Fillion and Stana Katic, on Wednesday celebrated their upcoming 100th episode (which airs on Monday, April 1 at 10 p.m. ET) with champagne and a very clever cake.

The show’s star, Fillion, took some time to thank his fellow cast members for the journey they’ve endured thus far.

“If you know me, and you guys do know me, you know that I don’t like to learn anything,” he said at the celebration. “But despite my best efforts I have learned in 100 episodes how much I rely – how heavily I rely – on all of you.”

“When people tell me, and they do, that they love this show I don’t think of the polished piece that we see on TV, I think about the hours we pull, freezing outside, the laughs, hanging out,” he continued. “I appreciate you all, and I look forward to coming to work and being with you all, all the time.”

The series, which is currently in its fifth season, debuted in 2009 and follows a successful mystery novelist, Rick Castle (Fillion), who gets permission from the Mayor of New York City to tag along with an NYPD homicide investigation team for research purposes. Katic portrays Detective Kate Beckett, who over the seasons has developed a romantic relationship with Castle.

The air date of the 100th episode is also Castle’s birthday — April Fool’s Day.

OTRC.com, parent company KABC Television and the ABC Television Network are owned by the Walt Disney Company.
