The Season Four finale of 'Pretty Little Liars' is less than three weeks away and based on information from the show, it will be the episode in which Ali tells all. But just what will she reveal?

Continue reading to find out and as always be wary of spoilers. Obviously.

As the synopsis for the episode 'A is For Answers' (4x24) reveals:

After years of questions and mystery surrounding the night Alison DiLaurentis disappeared, her four best friends come face to face with Ali and finally earn what really happened to her that September night.

Now with their newfound knowledge of Ali’s long-held secrets, can Aria, Emily, Hanna, and Spencer help Alison finally figure out who ‘A’ is?

Meaning that in addition to Spencer recalling the events of the sleepover, Ali will explain to the Liars in her own words what happened.

We'd also love to hear where she was for the first four seasons of the show and how she feels about Ezra's recent revelation considering their relationship with one another. Also, whether or not he was in fact with her the night she died.

There will also be an "epic" flashback sequence between Ali and Mona, so we cannot wait for that.

As executive producer Marlene King has teased, this is the "season of answers." You know, one in which "lives may or may not be destroyed" according to actor Ian Harding, who plays Ezra.

Either way, it's bound to be a thrill ride.

The next episode of 'PLL' airs on ABC Family at 8PM ET on Tuesday, March 4.
