The episode begins with a Nebula 9 experience and we see that a woman is just lying around. She appears to be a part of the show but later we see that she is actually dead. Richard is signing his copies of the Storm Season. Kate arrives declaring that there is a murder that took place in the Supernova Convention. Shiny! He tells her that he used to attend this convention every year with Alexis and he feels that it is a genius idea to commit a murder here. Alexis used to dress up like Princes Leah and he was Dart Vader. Castle doesn’t seem to be a fan of Nebula 9; but he seems to like the ship despite the show being lame. The victim is Annabelle Collins. ..
