Why is Toby Punching Caleb in This New 'Pretty Little Liars' Promo?!

Things are looking pretty ugly in this brand new promo for Pretty Little Liars!

The upcoming back half of season six jumps ahead five years, and the girls have been without “A” the whole time!

But that doesn’t mean things are all peachy in Rosewood.

In fact, the biggest shock of the promo is when Toby (Keegan Allen) punches Caleb (Tyler Blackburn)!

We don’t know why he does it, but look who’s standing next to him – Spencer (Troian Bellisario)!

Do you think maybe Caleb and Spencer hooked up? Watch below and tell us what you think!
