“A” is an unpredictable sort, and her targets and tactics often change with the weather. Who will she target in Season 4 of Pretty Little Liars? From what we know or what we think we know here are our top speculations:

Caleb Rivers

Unfortunately, Caleb (Tyler Blackburn) was absent from the Season 4 premiere - an absence that would have been sad, but with his impending departure was downright tragic. We still can’t really comprehend what series of events will occur for Caleb to decide to up and move to Ravenswood, but we’re betting it involves “A.” The villain seems to take a particular joy in keeping these two apart. We think in Season 4, she might find a way to do it for good.

Ashley Marin

Speaking of poor old Hanna, we suspect Ashley Marin (Laura Leighton) is going to be an uber target this season. She was targeted in the Season 4 premiere - “A” put her phone into Wilden’s casket - and we think that’s just going to continue. We’re not sure if “A” would care especially about Ashley if the Marin matriarch hadn’t made targeting her so easy. The police video footage of Ashley running down Wilden and then fleeing the scene of the crime makes for particularly potent blackmail material, don’t you think?

Ella Montgomery

Ella (Holly Marie Combs) has remained relatively unscathed by “A,” aside from the drama that was Byron’s affair (which we actually blame Byron for more than “A”). With Season 4 hailed as the PLL season with parents as targets, we think Ella could be a major mark. We haven’t seen that cafe-running younger boyfriend of her’s in a while, but we want to and it seems like exactly the kind of good thing that “A” would try to ruin. She loves killing other people’s love.

Speaking of parents, Nia Peeples (Pam) has us really worried about her onscreen alter ego. Not only did she tweet that we could “expect desperation” from Pam in the first episodes of the season, but she will be crying in Season 4, Episode 8: “The Guilty Girl’s Handbook.” Yikes! As of last season, Pam is not only Emily’s mother, but an employee of the Rosewood PD - which we imagine makes her doubly as exciting a target for “A.”

Toby Cavanaugh

PLL producer Oliver Goldstick said that, this season, Toby (Keegan Allen) is going to get pulled back into “A”’s vortex, and it’s already started! In the Season 4 premiere, we saw Spencer’s boyfriend clandestinely moving the mobile “A” Team lair in exchange for information about his dead mother. And he didn’t mention a thing to Spence! Oh, Tobes, you’re making the same mistakes all over again. We’re not sure what went down with Toby’s late mother and we don’t blame Toby for wanting to know, we just hope he knows what he’s doing...because “A” definitely has her eyes on him.

Are you as worried about these characters as we are? Who else do you think is going to be a major target in Season 4? Let us know in the comments below!
