The revelation that Toby Cavanaugh (Keegan Allen) is part of the "A" team turned the Pretty Little Liars world upside down. But the cast didn't always know Toby was going to be the one who betrayed the girls. In fact, they actually filmed several alternative endings to Season 3, Episode 12: “The Lady Killer,” each revealing a different person as part of the "A" team.

One of the alternates was Caleb (Tyler Blackburn), which is crazy to think about. How did Tyler Blackburn feel about that possibility? We caught up with him, and got his thoughts on the "A" team, Haleb, and what's coming up for Caleb in the Season 3 winter season.

Wetpaint Entertainment: So you’re not going to be on Team "A," for now.

Tyler Blackburn: No. I mean, it was always an alternate ending that Caleb could be on the A Team, but they went with Toby. But I was prepared for either way. I'm fine with it. I like the idea that he's kind of the knight in shining armor, too. That's a cool part to play.

So you shot the hoodie scene. How was that?

It was cool. It was really cool. So, yeah, I was ready for anything, and I shot that scene. And I was like, “Well, we'll see what happens,” and then they were like, “It's definitely going to be Toby.” And I was like, all right.

What happens in spring for Caleb?

Well, there's a lot of family issues that Caleb's going to have to deal with that definitely bring me and Hanna close together. It causes a little bit of waves, but in the end it brings them closer together and makes their relationship even stronger. I'm just waiting for them to get married or something. I feel like they've been through so much. It's like, dude, just get married already and have babies.

Where's the fun in a happy relationship?

I know.

What's going to tear them apart?

At this point, I really don't know. I mean it would have to be something pretty big. I'm wondering if it's going to come out that she kissed Wren.

You would think. Not where you're at right now?

Yeah. It might come back to bite you.

Is Caleb more of an ally now to the girls?

Oh, yeah.

Are they letting him in more? Where does the mystery part take them?

For him, specifically, he doesn't become the fifth PLL necessarily. [Jokes] Yes, let me just change the intro. It's like all the girls in a row, and I'm laying on the coffin in front of them. [Laughs, and mimics Lucy Hale by putting a finger to his lips.] No, but, he definitely lends a hand, for sure. And I think also now Hanna is even more protective over him because he was so near death with being shot. So, yeah, nothing that I can really talk about, but it definitely comes full circle. And he helps them.

Is there an episode you're really excited about? Something that's going to turn everything on its head?

I think every episode has something like that. I can't think of a really good answer for you on that to be honest, but I know that there's just some good stuff in general with everybody. There are so many cast members they have on the show that it's inevitable that so much is going to happen.
