The men of Pretty Little Liars are causing trouble.

'Pretty Little Liars' Season 6: Emison To Get A Chance In Season Of Romance? Marlene King Teases Alison/Emily

From Ezra's (Ian Harding) terrifying tirade to Toby (Keegan Allen) and Caleb's (Tyler Blackburn) fist fight, the guys of Rosewood will return from the five-year time jump with fire in their eyes. Romance is the watchword of the winter season, and it appears the 20-somthings may let their passions get out of control.

At least this seems to be the case with the formerly amicable Toby and Caleb. The cop can be seen lashing out at the computer whiz in the latest 6B promo, and TV Line thinks it has something to do with Spencer (Troian Bellisario). Belissaro's character is, after all, standing next to her former beau when he knocks poor Caleb right off his feet.

For now, Caleb's future remains a mystery. Allen, however, has talked about Toby's evolution, and his teasers have Spoby shippers biting their nails.

"For the people that are die-hard fans of the show, I think they are going to flip out," Allen informed Entertainment Tonight. "There are a slew of changes and it's kind of the way you'd want to see the show come together."

BUT, Allen was quick to point out that these new developments could leave viewers in tears, it all depends on what they're looking for.
