Castle Two-Parter Sneak Peek: '3XK' Has a Surprise for Rick and Kate

Loading video...

This Monday at 10/9c, as ABC’s Castle kicks off its annual two-parter, Rick and Kate come face to face with the notorious Jerry Tyson aka 3XK.

Or do they…?

In the sweeps event’s opening episode, titled “Resurrection,” when clues in a new murder implicate 3XK groupie/plastic surgeon Dr. Kelly Nieman (returning guest star Annie Wersching, 24), the team uncovers connections to Tyson.

But do they uncover Tyson himself? In the delicious sneak peek above, Rick (who is on hand to consult) and Kate have a lot of questions for their presumed-dead nemesis, though what the man (returning guest star Michael Mosley) across the table from them has to say is, in a word, somewhat unbelievable.
