Castle Season 4 Finale Spoiler: Fans Will Be "More Surprised" Than Ever

It's hard to believe the Castle Season 4 finale is just a month away!

It's been an action-packed season with twists and turns galore, but according to actor Jon Huertas (Detective Esposito), none of that will compare to what happens with our leads in the last episode.

“I think the audience is going to be surprised about what happens between Castle and Beckett," he told TV Line at the Genesis Awards on March 24. "More surprised than they ever have been.”

Last month, Wetpaint Entertainment spoke exclusively with Tamala Jones (Lanie Parish), who described the episode as one, big jaw-dropping "boom," both emotionally and literally.

"It is powerful," she dished. "Don’t know how they come up with the stuff they do, but these guys are geniuses in the writers’ room. I can tell you, if you thought last season’s ending was crazy, wait until you get a load of this one."

We hope the boom Tamala's talking about is the sound of the headboard in Beckett's bedroom. Now that would be surprising.
