'Pretty Little Liars Season 5' Finale Spoilers: Finally Big 'A' Mystery Resolved

"Pretty Little Liars" is ready to deliver a heap of surprises on its Season 5 finale this Tuesday before the show goes on an interminable hiatus.

In the episode titled "Welcome to the Dollhouse," the four best friends and fashionistas will have to ditch their enviable threads in favor of four tangerine jumpsuits.

It may be part of some dream sequence, but there's a probability that Aria (Lucy Hale), Emily (Shay Mitchell), and Spencer (Troian Bellisario) would be giving Hanna (Ashley Benson) some company in jail.

In the penultimate episode of the season last week, Alison was found guilty of Mona's murder, which will lead to the arrest of Aria, Spencer and Emily.

With their arrest, fans should expect all five of the girls sporting orange jumpsuits, giving Hanna some more company in jail.

At some point in the episode, "A" will target Ezra and Caleb after the guys attempt to find Mike, Entertainment Focus said.

"A" has always had fun playing with Aria, Emily, Hanna and Spencer, but now "they" have the biggest game to date in store for the girls.

As shocking secrets come to light and the biggest clue to the "A" mystery is revealed, is this one playdate the Liars can survive?

Either way, the press teaser tells us that "Dollhouse" will include the "biggest 'A' reveal ever" after five seasons of creepy texts, deaths, and hoodies, E! Online reported.

In a teaser video, some of ABC and ABC Family's biggest get in on the mystery including Dancing With the Star's new batch of celebrities Kelly Rippa and Michael Strahan, Tori Spelling, Lisa Rina, Jesse McCartney and more.

Catch "Pretty Little Liars" at 8 p.m. ET Tuesday on ABC Family in the U.S. and Netflix on Wednesday in the U.K. for the season finale.
