Are you sure you want to keep reading?


The PLL Season 3 summer finale betrAyal was hugely hyped before the episode. So who turned out to be working for the "A" team?

The betrAyer is...

Toby (Keegan Allen). It's Toby. Really. We see Mona (Janel Parrish) talking to someone in an "A" hoodie at the end of the episode, and then that person turns around and it is Toby. 

We … don't even know what to say. We are still processing.
