Sasha Pieterse’s excitement for Season 4B of Pretty Little Liars may just send us over the anticipation edge. Check out what Sasha had to tell Alloy Entertainment about the upcoming winter run and Alison DiLaurentis’ part in it…

“Our first episode for the second half is called ‘Who’s in the Box’ and I love the name because, it’s true, it’s one of the biggest questions,” said Sasha. “OK, well Alison’s alive, so who is in the grave? We have a lot to tell in the second half of the season and Marlene’s always said that this is the season for answers, and I have to say that the second half of the fourth season is by far my favorite out of anything we’ve ever done.”

OK, you had us at “Who’s in the Box,” Sasha (though, we have our own theories when it comes to the game of musical graves PLL seems to be playing). Though we’re excited to learn the grave-dweller’s identity, we may be even more excited to see how the Liars’ react to Ali’s return. We didn’t get to see much of the aftermath in the PLL Halloween episode, but it sounds like there is going to be some serious feels confusion...

“There’s a lot of grudges and I think the girls don’t know how to react,” Sasha spilled. “It’s an interesting dynamic because of how they left off with Alison especially, Spencer. So, the girls go through a lot in the second half of the season.” We’d say. And we’re dying to know what Spencer’s well-kept secret is, and if it has anything to do with the fight she had with Ali the night of her disappearance!

As for the aftermath of the other big reveal Ezra is “A” Sasha was staying mostly mum about how it will affect our girls: “Of course, Ezra: is he ‘A,’ isn’t he? But, here’s the thing, each girl not just Aria goes through a lot, and I think at the end of the day, it’s just reflecting on Alison and how they handle things with her. It’s a big season and the season finale is crazy.  It’s great.” OK, fiiine. We’ll watch it.
