Mona Vanderwaal's (Janel Parrish) back and scarier than ever on Pretty Little Liars Season 3B, and we can't wait to see what she's up to on the tantalizingly titled Season 3, Episode 15: "Mona-Mania!"
While we can't speed up time, we can make the wait for the new episode a tad more bearable by obsessing over spoilers. To aid in speculation, we've rounded up all of the juiciest hints about Episode 15 right here.

The Liars vs. Mona. According to the official synopsis of the episode, "after the shocking events at the school marathon, Aria [Lucy Hale], Emily [Shay Mitchell] and Spencer [Troian Bellisario] are sure now more than ever that Mona [Janel Parrish] is up to her old tricks." And apparently she's "seemingly popping up everywhere," which makes it look "like she has a plan. But with no real evidence to prove Mona is back to her evil ways, how can the Liars prove what they believe to be true?" Isn't that always their problem?
Hanna's hesitation. Hanna (Ashley Benson), on the other hand, is "holding out for her former friend" and therefore "isn't so sure" she's still evil. It definitely looks like Mona is doing her very best to convince the Liars she's a good guy now. Will Hanna's empathy get her into danger, or is she right to believe that Mona might have changed?
Aria's suspicions. Meanwhile, "Aria’s fears about her father grow stronger when something vital hidden in her room goes missing." Hmm ... sounds like Byron (Chad Lowe) is starting to look awfully suspicious.
Lucas and Jason. According to Brendan Robinson (Lucas Gottesman), we'll start to learn more about what's going on between Lucas and Jason (Drew Van Acker) this week, which hopefully means we'll get some sort of explanation for Jason's uber-suspicious wound.
A love interest for Spencer? A new character named Andrew Campbell will make an appearance this week. In the PLL books, Andrew is a major love interest for Spencer. It's unclear if he'll play the same role on the show, but he and Spence do have at least one scene together.
A party in the woods. In this sneak peek, Emily convinces Paige (Lindsey Shaw) to go to a swim team party in the woods. Based on this set photo, it looks like Toby (Keegan Allen) may join them. But is he there as "A"?
The return of Dr. Sullivan. It also looks like Dr. Sullivan is back this week.
