Ready to take a look ahead, Castle Fanatics?

On February 17, the murder of a high school mean girl will send Castle back to school...specifically his alma mater. Or at least one of them, considering he got kicked out of his share.

Will his less-than-stellar academic history affect Beckett's investigation into a murder?

However, look for Castle Season 6 Episode 15 to feature an even bigger twist that may make Rick smile: The possibility of a telekinetic killer!

Check out these preview photos for "Smells Like Teen Spirit," scheduled to air on Monday, February 17 on ABC.

And don't forget you can always watch Castle online right here at TV Fanatic.
