Spencer may hook up with Caleb, the ex-boyfriend of Hanna, and that will create a friction between his friendship with Toby, according to the new spoilers for "Pretty Little Liars" season 6B.

The girls are back in Rosewood about five years have passed as the trial of CeCe, who was revealed to be "A," will bring them together.

But things will be drastically different for Aria (Lucy Hale), Spencer (Troian Bellisario), Hanna (Ashley Benson), and Emily (Shay Mitchell). For one, Hanna is already engaged, but not to Caleb. Aria will find somebody new, and Spencer will have a new man in her life, and it's rumored to be Caleb.

"In the new Season 6B promo video there is a clip that features Officer Toby punching Caleb right in the face, and dropping him to the floor," said Celebrity Dirty Laundry.

"All while Spencer watches on the sidelines in shock! Seeing as how Caleb and Toby used to be besties, and they both had a mutual interest in protecting the liars, an affair between Caleb and Spencer seems like the only logical explanation for their fight."

But this being the "Pretty Little Liars," their romantic liasons are the least of the worry for the girls as there would be a new baddie in town.

Showrunner Marlene King teased spoilers for "Pretty Little Liars" season 6B to Hollywood Life when prodded for the new villain.
