We know Rick can always count on Kate to have his back but what's so shocking that it put that look on her face?

It looks as though Richard Castle, Private Investigator finally has a real case that will allow him to use his fun gadgets. He must be thrilled.

Rick really doesn't need those binoculars when the person he's following gets that close. It looks like Rick's been busted.

Is that the wayward husband that Castle's been hired to follow? Is he more than just unfaithful, could he be a murderer as well?

We have to wonder what's got Kevin Ryan looking so darn worried on this episode of Castle.

We're guessing that maybe Ryan realizes that Castle has found his own special brand of trouble once again.
