Dexter urges Travis to think what Gellar will do next, and Travis reveals that the professor offers a way back to him.
Dexter is getting a help from an unexpected source in the next episode of the crime drama series. After getting approached by the blood spatter analyst/serial killer, Travis will help Dexter to find his former mentor, Professor Gellar.
Travis claims he does not have a clue what Gellar will do next, but he shares to Dexter that Gellar has offered a way back to him. Looking reluctant, Travis may answer Gellar's invitation as he shows up in front of the professor in a scene from the preview of the upcoming outing.
Dexter appears to understand the symbols found in the Doomsday case, leading his sister Debra to question how he knows about this.
"Get Gellar" will air Sunday, November 27 at 9/8c on Showtime.
"Dexter" has recently been renewed for two more seasons.
