Spoiler alert! If you haven’t caught up on Castle’s second season finale, Stana Katic will spoil it for you. Last we saw detective Kate Beckett (Katic) and novelist Richard Castle (Nathon Fillion) the two parted ways for the summer.

“We kind of have to figure out what’s going on with his [Castle’s] ex-wife,” Katic told On The Red Carpet’s Rachel Smith at the recent “Mummies of the World” event at the California Science Center in Los Angeles. “He went to the Hamptons with his ex? What’s up with that?”

Not only did Castle go to the Hamptons with his ex-wife, but he is also contemplating ending his partnership with Beckett because, as he tells poker buddy James Patterson during the finale, “I think I’ve gotten everything I can out of that relationship anyway.”

“We’ll have to figure out how he comes back into the fold,” Katic says. “I’m sure Kate started dating someone or something like that over the summer. You know she’s a happening girl.”
