The Season 5 finale of "Pretty Little Liars" promises to be a jaw-dropping episode where viewers will finally find out who "A" is.

In a recent interview with Entertainment Tonight, "Pretty Little Liars" executive producer, Marlene King describes the season finale as "shocking," "action packed," and "demented."

"I think we're going to break Twitter all night long," he added.

King reveals that the finale will delve into the history behind the mysterious dollhouse and fans will finally be able to get a full grasp on who "A" really is.

"It is the biggest reveal we've ever given so far. In so many ways you will know who this person is, but I will just say there is a little bit more story left to tell after the episode -- not a lot of story, but a little bit," she explained about the big "A" reveal.

But the biggest thing that might shock fans about "A" is that they learn "A" has feelings and is compassionate.

"There's a line and I'll tell you what it is -- it's a spoiler and I don't think we've told this line to anyone. A certain character in this finale says something like, "Oh my God, 'A' has a soul,'" King reveals, adding, "That to me tells us yes we're ramping up to the end of this story -- but it's not just pulling off the mask of 'A', it's really finding out that 'A' is human too and 'A' has a soul like anyone else."

In a separate interview with the HollywoodLife.com, another "PLL" executive producer, Oliver Goldstick, revealed that during the finale, fans will find out who Andrew Campbell truly is apart from who he claims to be.

He also revealed that fans would see tension between "PLL" couples Ezra and Aria, and Spencer and Toby.

"The events of the episode sort of make you go, 'Wait, why would you leave the police department when you have great insight?' Basically, the question becomes, 'Why would Toby leave when he needs that badge now more than ever?'" Goldstick added.

The "Pretty Little Liars" finale airs Tuesday, March 24 at 8 p.m. EST on ABC Family.
