There’s a ghostly connection on the February 10 episode of Supernatural, which has a title that was recently appropriated for another TV series.
“Halt and Catch Fire” is the name, and here is how The CW describes the episode:
GHOSTLY CONNECTION — A ghost starts killing people through various electronic devices. Sam (Jared Padalecki) and Dean (Jensen Ackles) discover who was killed and why this ghost is seeking revenge on a group of college students but what they can’t figure out is how he’s doing it. With three dead, the brothers must stop the ghost before he claims his next victim. John Showalter directed this episode written by Eric Charmelo & Nicole Snyder (#1013). Original airdate 2/10/2015.
