'Pretty Little Liars' Season 7B Spoilers: Promo Teaser Reveals Four Characters As A!

"Pretty Little Liars" will finally reveal the true identity of A when it returns. The recent promo of the TV show teased the different characters that could be A.

Freeform released a new promo for "Pretty Little Liars" Season 7B and it looked like A's identity will soon be revealed. The promo clip featured the Liar's good moments including Hannah kidnapping Noel, Elliot diving headfirst into the girl's windshield and Spencer's hookup in the elevator, TV Line reported.

The unmasking of A.D. in "Pretty Little Liars" Season 7B will not be easy because a number of characters are suspect. Ezra (Ian Harding), Mona (Jannel Parrish), Dr. Rollins (Huw Collins) and Mary Drake (Andrea Parker) are all dragged into the controversy behind A.D.'s identity, per Bustle.

All four had intriguing past, secrets and scenes in "Pretty Little Liars" that will make one suspect them as A.D. For instance, initially everyone thought Ezra was A but it turned out that he was just researching a true crime book. Also, it's thought-provoking whenever Spencer shouted the words, "He's frickin' A!"

In the previous seasons of "Pretty Little Liars," Mona had been an A before. Thus, there are chances that she could be A again.

On the other hand, the Liars already buried Allison's husband after running over him. However, Dr. Rollins could still be alive and could be A. The recent "Pretty Little Liars" promo featured him peering through a window, which suggested about his impending return.

Meanwhile, in the first part of "Pretty Little Liars" Season 7, among the big revelations was Mary Drake being Spencer's biological mom. However, there were rumors that she would have a bigger role and that she was involved in some dark deeds.

Aside from the four characters, Wren Kingston (Julian Morris) was noticeably absent in the "Pretty Little Liars" Season 7B promo. Could his absence mean more?
