It looks like "Castle" is taking a leaf out of the recently concluded "American Horror Story-Coven" book, as the murder mystery involves one of the Seven Wonders, telekinesis. The episode 15 of "Castle" Season 6 is titled "Smells Like a Teen Spirit." This episode will take Castle to one of his alma maters.
Castle and Beckett will be called upon to investigate the murder of a school girl. She is likely to be part of a group of mean girls, the odd-cast [sounds like Madison of coven]. The main suspect of "Smells Like a Teen Spirit" is a teenager who can perform telekinesis. There is no doubt that Castle will be excited like a child to discover that the crime possibly involves telekinesis. If not alien powers, occult powers will just work great for Castle. For Castle, some day, aliens may also descend upon New York to prove his bizarre theories right. In "Smells Like a Teen Spirit," Castle and Beckett will realise that they are in a "real-life Carrie" situation.
Stephen King's epistolary novel, "Carrie," features a teenage outcast who uses her telekinesis powers to exact revenge on her bullying classmates. The revenge costs lives of many innocent people and almost destroys her fictional town.
In the previous episode, "Dressed to Kill," Beckett and Castle decided to get married as soon as possible. The two did not decide on a date, but Beckett and Castle had no qualms about getting married this spring. Now that Beckett has a wedding gown, hopefully, it will not take too long for this very much in love couple to announce a wedding date. In the new episode, there might be a scene of Caskett further discussing their wedding.
