Castle's sexy season premiere this fall will give fans everything they've always wanted. The ABC drama picks up in the moments following Beckett and Castle's heated race to the bedroom. "We think it's important to show the fans what this moment means for Beckett and Castle and how it may change and complicate their relationship," says creator Andrew Marlowe. That's right — Marlowe said relationship! He believes Moonlighting made "a big mistake" by breaking up its leads right after they did the deed, so "we're taking a much different approach [and showing] the fun of being in a relationship."

On the non-romance front, Alexis will keep her internship at the police station even after she moves to her college dorm, Ryan and Esposito are still on the outs and the mystery of who killed Beckett's mother will finally be solved. "We do want to give Beckett some level of resolution," says Marlowe. "It's time to move beyond that mystery, but it leads to an explosive confrontation."

Now, might Castle and Beckett move beyond dating to perhaps marriage and baby? Not anytime soon. Adds Marlowe, "After two failed marriages, he worries about screwing it up, and she worries about being wife No. 3."
