Pretty Little Liars Season 5 spoilers: 'A' will be revealed by finale and Alison to turn dangerous for the liars?

Pretty Little Liars' fans need to be more attentive with each remaining episode of Season 5 as the show producer has teased that many PLL fans will be able to guess the real identity of 'A' by the finale.

"By the end of this season I am sure some people will guess correctly and for the right reasons," King tweeted after the airing of episode 15, Fresh Meat.

The lairs, Aria, Hannah, Spencer and Emily are still suffering in their personal lives and are blaming everything on 'A' who is still hunting them. This might prove to a certain extent that Alison is not the dreaded villain of Rosewood as she is in jail for her possible involvement in Bethany and Mona's murder.

Ali, on the other hand, may not spare her former friends when she gets a chance to escape and the former queen bee might prove fatal for the pretty liars during the rest of the episodes of Season 5.

"Ali's used to being in control, so when you strip away all of the things that work for her, I think you're going to get down to the core of who she really is, which may not be pleasant — or may be, surprisingly. She may come out of the slammer a better person — we'll just have to see," show producer Joseph Dougherty told Hollywood Reporter about the future turn of events.

He also teased that it's a "dark ride" for the rest of the season which will feature some of the scariest scenes ever filmed in the show.

"This is some of the most aggressive storytelling we've done in the history of the series. To quote my title for the holiday, "It's a Dark Ride." If you can watch it live, don't watch it alone — we've got some pretty hairy stuff coming up."

Pretty Little Liars Season 5 airs every Tuesday night on ABC Family.
