The filming of Pretty Little Liars Season 3 is coming to the end, and you know what that means — the cast now knows a ton of new secrets.

We recently had a chance to chat with none other than the most surprising new villain on the show, Keegan Allen (Toby Cavanaugh), at the TV Guide Magazine Hot List party. While he kept pretty tight-lipped about what's coming up, Keegan did spill on what it's like to play a bad guy, whether he thinks there's hope for Toby/Spencer (Troian Bellisario), and what we can expect from the 3B finale.

Wetpaint Entertainment: What’s been the best part of playing bad guy?

Keegan Allen: The best part about playing the bad guy for me is I get to play a role I normally don't play in real life. So everybody likes to be able to feel bad — without the consequences. This is really bad, so that's good.

You like playing the bad guy.

Yeah, I've enjoyed it. I've had the privilege of playing both the good and bad guy now. He started out as a good guy and now he's bad.

Ever miss playing sweet version of Toby?

I mean it's a hard question to answer because it's still kind of gray because the characters on the show don't know he's a bad guy yet. So he gets to play both sides. I get to play that middle ground, still.

Personally, do you think Spencer/Toby could survive?

Personally, I like to believe anything is possible.

Will the 3B finale be just as shocking as the 3A finale?

Yes, we're filming it currently, and it's shocking. Even reading the script, unbelievable, I can't wait to see how it plays out. You get so much closure, yet it brings a whole slew of new questions and crazy stuff.

What can you tease about the finale?

I can tell you it's going to shock everyone in the world.

Will we narrow down suspect list in 3B?

It's already narrowed down. I'm "A"!
