"Pretty Little Liars" Season 6 is wrapping up its summer run next Tuesday and fans are raving about the biggest revelation that's about to happen. Just a few more days and fans will get to finally meet the person behind "A" after suspecting a number of characters for the past five seasons.

Next Tuesday, fans will finally get a glimpse of the real face behind Charles/"A"; however, the main concern of many fans now is the justification of whoever may be behind all this masquerade act for over five years now, as per Hollywood Life.

Last time the show tried to expose the identity of "A," fans were just introduced to the helpers of this mysterious being. And now that the biggest revelation in the show is about to happen, many are wondering if the justification will be something believable. After all, "A" should be someone who was present in the many happenings in the previous seasons.

On the show's official "PLL" Facebook page, many fans shared their opinion on who "A" could possibly be.

One fan by the name Andrea Megie Melegova wrote: "I think that 'A' kidnapped Kenneth or Kenneth is 'A!' Jason can not be 'A' because in last episode met with 'A.'" 

Another fan by the name Benita Burzynski commented: "I don't want it to be Maya because we haven't seen her in too long, same with CeCe. I really want it to be a guy. But from Alison's reaction I really think the 'omg' was a 'omg-you-are-alive?!"

Facebook user MichaelGabrielle Igancio Nable noted: "As much as I want to spare my fave characters but I want Caleb to be Charles. And I want Aria to have something to do about everything too. Then, that'll be heartbreaking. And it would live up to a lot of people's expectations."

Meanwhile, ABC Family already dropped the first two minutes of the "PLL" midseason finale episode and it looks very interesting.

In the clip, Ali tells Charles, "I'll do whatever it takes to help you!"

Spencer says, "Just because we know who you are, it doesn't mean the game is over."

Aria says, "You spent your whole life trying to get back to your family. It's not too late."

The clip ends with Hanna telling Charles/"A," "You've been a bitch to us, but we heard your story. We understand!"

Because of her words, TVLine reported that something is quite off since Hanna called Charles a b—h. Does this mean Charles is a woman? There is also the question if the person behind "A" is going to die in next Tuesday's episode. Find out next week by watching "Pretty Little Liars" Season 6 Episode 10 or the midseason finale of the show.
