Castle Season 6 Episode 15 sent Castle back to his alma mater where he was kicked out senior year for a prank involving a cow. Unfortunately the principal still remembers Rick Rodgers.
But when telekinesis appears to be the method for murder, Beckett is skeptical. Was it an outcast girl with supernatural powers or a simple case of special effects in action?
And when Rick and Kate realize that they don't have a song to dance to at their wedding it takes a high school dance to help them narrow it down.
