And then there were two.

After Tuesday’s reveal on Pretty Little Liars that Toby Cavanaugh (Keegan Allen) is the betrAyer we’ve been waiting for, Janel Parrish (Mona Vanderwall) and Keegan addressed the shocker in a new video interview from ABC Family.

In the “A”-on-“A” interview, Keegan reveals that he has known about the twist since early on in the season. Clearly we underestimated his secret-keeping skills. Keegan says that when he first heard the news, he thought it was a joke. We wish!

But Keegan does agree with us on one thing: The twist was utterly shocking because Toby WAS the “most trustworthy character in Rosewood.” Or was he? If he’s been on the “A” team all along, was he ever trustworthy? Regardless, we miss the days when he at least seemed to be so trustworthy. Now that six-pack is tainted forever. What a waste.

Keegan goes on to discuss his first time in the hoodie and the ability to become an “anonymous evil shadow.” It’s all so creepy.

Our wounds need some more time to heal before we can discuss more “Toby is ‘A’” drama. So as Keegan puts it at the end of the interview, “If you’ll excuse us, we have some work to do.”

However, our work doesn’t involve betraying the person we love most. Oh, Toby. How could you?!

We can’t go on. Watch the video for yourself below!
