A lot is going to go down on the season finale of "Pretty Little Liars," which premieres Aug. 28. In episode 12, "The Lady Killer," the Little Liars will have fresh blood on her hands and Ezra's ex-girlfriend might be revealed, Wet Paint reported.

Emily, played by Shay Mitchell, has an empty and shocked look on her face as an officer seems to question her.

A close look at the photo shows blood all over the front of her clothing and she looks like she is rubbing her bloody hands together. Her make-up is runny and she is covered in dirt. From the picture it seems certain that Emily was involved in a bloody altercation.

A photograph of Paige at the crime scene was also revealed, but she is not covered in blood nor does she seem unkempt in any way. In fact, she looks vaguely annoyed.

Whose blood is Emily covered in? Did she discover another dead body or was she caught in a confrontation with Maya's murderer and another person?

There also are photos that reveal a mystery girl talking to Ezra. One of the most shocking episodes was when Ezra revealed that he had gotten his ex-girlfriend pregnant in high school, but that his mother gave the ex, "Maggie," money to "take care of it." But no one knows where Maggie is or if she actually "took care" of anything -- meaning it's quite possible that Ezra could be a father.

In the pictures obtained by Wet Paint from ABC Family, the mystery girl who Ezra is talking to might look familiar to some. It's actress Larissa Oleynik, best known for playing Bianca Stratford in "10 Things I Hate About You," with Heath Ledger, Joseph Gordon-Levitt and Julia Stiles. She also stared on Nickelodeon's hit 1990s show, "The Secret World of Alex Mack."

Could she be playing Maggie? Had Ezra not told Aria everything? After all, he could still be on the "A" team.

Who do you think Larissa Oleynik is playing?
