Rick always had a penchant for resorting to theatrics, but he always had a strong moral compass. But according to "Castle" season 7 spoilers, his very character is being questioned when he witnesses a murder.

In the latest episode, it seems like Rick bit off more than he could chew. Fans would remember that the book author was kicked out of the 12th Precinct and barred from working with authorities after his link with the mob boss was discovered.

To continue doing what he loves, Rick took an online course and secured his P.I. certificate.

Thankfully, being separated from working with Rick's wife, Beckett, has apparently not affected their personal relationship.

The network released a clip of the upcoming episode where Rick watches somebody dragging his client's body. Nathan Fillion's character then follows the vehicle and sees the perpetrator dumping the body. Before he can call for assistance, however, he's knocked unconscious in the upcoming "Castle" season 7 episode.

Then it's like the "boy who cried wolf," since nobody believes Rick even when he insists that his client was murdered.

The case has a much greater significance because it could be linked to Rick's disappearance during his wedding day. This time, Dr. Kelly Neiman-a disciple of 3XK, could be involved.

David Amann, showrunner of "Castle," told TV Guide: "The case he's involved with that has some emotional intensity ... brushes up against his experiences that occurred while he was missing."

The synopsis for "Castle" season 7 offered some spoilers as it reads: "Castle is hired to uncover if a client's husband is having an affair, but the case takes a shocking turn when Castle witnesses the client's murder - by her husband. But with no proof that the killing took place, Castle and Beckett must investigate to expose the truth."

Watch out for more "Castle" Season 7 spoilers which will be published when they come along.
