We've been promised that ALL of our questions will be answered in Season 7B of Pretty Little Liars. This means that we should find out which PLL ships are endgame, who killed Charlotte, and most importantly, who A.D. is. With that in mind, we thought we'd come up with some possible things A.D. could stand for. Check them out below and then vote for the option you think is the right one.
1. Alison DiLaurentis
Is it crazy to think that the A-Game could end right where it began? With Alison DiLaurentis. Yes, A was actually Mona pretending to be Alison, but we all thought it was Alison and there was a reason for that. She knew all of the Liars secrets, their little weaknesses, she was the queen of playing games, and she definitely had a dark side. Is it possible that her dark side has come back with a vengeance? Could she never really have forgiven the Liars for them getting over her "death"? Did she plant the red jacket in her room as a test to see if the Liars would trade her in to save Hanna? It's possible.
2. Ali Dee
If you've got a good memory you'll remember that Ali Dee was actually the name that Mona had on her pass to get in and out of Radley. This girl's played the A-Game before, would she do it again? The board game certainly has a Mona-esque feel to it. Would anyone else be smart enough to build it? Well, Caleb would be, but no, we are NOT going there...
3. Aria's Dad
Admit it, this guy is SKETCHY. And he's a rule-breaker, but would he go as far as to torture the girls? We can't really see it, but with PLL, you never know...
4. Addison Derringer
Ali's mini-me, an irrational hate of Emily, natural stalking abilities, blackmail tendencies, a steely gaze... Oh, and her initials actually are A.D. She's got to be a red herring, right?
5. After Death
Let's face it, just because a character has died on PLL, that doesn't mean that they're actually dead, does it? Alison wasn't really dead, Toby wasn't really dead, Mona wasn't really dead... Which means that A.D. could be Maya, or even Nate!
6. Avenging Death
Or A.D. could be someone who is avenging someone's death -- there's quite a few possibilities there too!
