'Castle' Season 8 Episode 15 Spoilers: Kate shows off her fighting skills

All you fans of the hit TV series 'Castle' better be ready and prepared as we will be seeing a never before seen side of Kate in this week's episode of the show. So to help you get ready for some action packed episode, here are some spoilers for you to read on. Enjoy! 

In "Fidelis Ad Mortem," the promo posted by Spoiler TV shows that Kate will return to the New York Police Department Academy but not to visit. She is there to investigate the murder of a recruit officer. In the clip, Rick (Nathan Fillion) confirms with his wife the theory that the murderer is a fellow trainee. Kate tells him that they have 14 suspects who have all been trained for months on how to catch bad guys. She cautions Rick that they will have to use every trick they have to flush out the killer and make him/her pay for the crime he/she did. 

She will be seen spending most of her time on the training grounds as she eyes the recruits and find out who the murderer is. You can see Beckett back at her old academy training grounds, where she gives a little bit of hands-on “instruction” to a cadet on the proper way to ensure that someone is arrested. 

The scene shows how bad-ass Beckett is as she still lands on her feet while being the guinea pig in the training. After telling the woman that she needs to improve on her technique, Kate demonstrates how to properly throw an opponent using a few moves.
