‘CASTLE’: THREE BURNING QUESTIONS
While sifting through all the amazing tweets of thanks I’ve been sent this week in response to the Castle article in EW’s Fall TV Preview, I realized that there were a few burning questions many of you had. So I’ll go ahead and tackle those now!

+ Will Beckett and Castle stay together for good?
While I won’t say “for good” (because there’s just no way of me looking that far into the future), I will echo what creator and executive producer Andrew Marlowe told me: “I think it would be unfair to the audience to have them invest all this time and all this time together only to pull the rug out. I think that was one of the fundamental mistakes they made in Moonlighting. They got them together and then they split them up.”

+Is Maddox the big bad this season?
Well, if you didn’t already hate this guy, you’ll definitely hate him in the premiere — largely because he’s the thorn that bursts our happy couple’s Bubble of Happiness. “When we left last season, we know that whatever bubble Castle and Beckett wake up in, she’s still under active threat,” Marlow reminds us. “And in the last scene, Maddox said, ‘When I have those files, I’m going to put Beckett into the ground.’ And we know he’s close to getting those files. So as is often the case, in a moment of bliss, real life intrudes and the characters have to deal with that and deal with it in a new way, given where they are in the world.”

+ Will there be a two-parter this season?
Maybe. And if we see one, it will not be like any of the ones from past seasons. “We’ll probably do something different — something a little more personal,” says Marlowe.

WARNING! DOES CONTAIN SPOILERS!!
Zap2it have seen the season 5 promo of Castle and this is the news they had to dish.

The Heat Is On: Don’t expect any morning-after regrets between Castle (Nathan Fillion) and Beckett (Stana Katic). As we saw in the recent promo for Season 5, the pair are positively glowing. And both enthusiastically agree that their night of passion was no one-time (or, four-time!) fling. As they get busy making up for lost time, you can count on their transition from colleagues to lovers to be perfectly natural (unlike many fizzled TV pairings) and absolutely adorable.

Our Little Secret: One of the most entertaining aspects of the premiere involves Castle and Beckett’s efforts to keep their romance a secret. We’re not sure how long they can contain the news (or themselves), but as showrunner Andrew Marlowe told me after the epic Season 4 finale: “Once people get together, there are plenty of fun challenges, relationship obstacles to overcome [and] really uncomfortable, great, wonderful, crazy, challenging moments that they’re going to have to face.”

New Big Bad: In addition to a brand-new villain, Season 5 introduces one big badass…and her name is Kate Beckett. Emboldened by her updated relationship status, Beckett finds a new confidence — which she needs to cope with the latest threat from the conspiracy surrounding her mother’s murder. How she copes will amaze you — Beckett does something so shocking and unexpected in the last scene that you’ll be more excited about the episodes to come than ever before. We guarantee it.
