Look, as far as I'm concerned, there is no such thing as a bad episode of "Castle". However, there is a discrepency in the episode "Kill Shot" that bears mentioning. It isn't noticed until Castle is explaining to the team the meaning of the paper dolls. When he holds up the one called "The Persecution of Kings', the captain says "Henry Wyatt was killed on King Street." HOWEVER. The first place that they found that the shooter shot from was the place from which Henry Wyatt was shot from. The second "hide" they found, Esposito found the moleskin, and the lighter colored paper doll was the place from which Sarah Vasquez was shot. In order for the dolls to be correct, the Persecution of Kings paper doll had to be in the room where Sara was shot from, not where Henry was shot from. Since the first"hide"they found was where Henry was shot from, they should have found the Fall from Grace(yellow) paper doll.
I've probably confused you with this,..sorry. If you go to the link below, you'll understand. It is the subtitles for the hearing impaired for this episode.
