As "Pretty Little Liars" season 4 looms to its season finale, cast members Shay Mitchell and Sasha Pieterse took the time to discuss a very popular couple's fandom on the series: Emison.

"I think it's kind of amazing," says Mitchell to E! Online. "I had a hint of how big it would be when they found out [about their past], but now, I'm even more shocked with everything. You think it's going to be big, but you don't realize how big the reaction is actually going to be."

And although Allison has been confirmed to be alive in "Pretty Little Liars," Emily is still in a relationship with Paige, which could complicate things with Allison.

"Let's just say there are a lot of fans for Emison, and there are also a lot of Paily fans that are like, what's going to happen to Paige and Emily? And to be honest, I don't know," admits Mitchell.

So what spoilers do they have about the future of Emison?

"That's a [creators'] question. But I'm excited to see where Emily and Ali's relationship goes, especially knowing where it left off. So I'm very excited for #Emison—gotta use my hashtags right!"

Although we know the "Pretty Little Liars" season 4 finale will deal with the fallout of Ezra being discovered, one character who may get some spotlight is Allison's mother.

"Honestly, I think she learned all these bad habits from her mother, and her mother is very manipulative," says Sasha Pieterse.

"She's scarred by that emotionally and physically, and so I think once she learned that she had that power over someone, she used it to her advantage and she used it a lot, time and time again."

And as "Pretty Little Liars" nears its season 4 finale, spoilers confirm that many answers will be unveiled.

TVLine reports that Allison herself will reveal what really happened the night she went missing!

Could Allison's mother have something to do with that tragic night?
