Color us intrigued by the Pretty Little Liars winter premiere sneak peek that sees Hanna digging up the dirt (perhaps, literally) on Sara Harvey, aka a missing girl from a nearby town who may or may not be the corpse buried in Alison’s grave. Who is this Sara Harvey character? We speculate below.

What we know

The big question in the Season 4B premiere (and potentially the entire half-season) is “Who’s in the box?” In this sneak peek, we see Hanna suggest that the corpse in question is one Sara Harvey, a petite blond girl who went missing around the same time Alison did. As Sara is of the same height, build, and complexion as our girl Ali (get in line), Hanna suspects that she may be the girl buried in Alison’s grave. What else do we know about Sara? Well, her parents think she ran away with some boy. And her friends are looking for her. They have a website set up seeking information on the missing Cortland teen. It’s not only where Hanna got all of her information, but also how she contacted Sara’s group of friends. (Does anyone else feel like we’re being set up for a whole other group of Liars?)

What we want to know

We only have about a million questions concerning Sara Harvey. Did she know Alison? Did she know “A”? Could she still be alive? If she is the body in Alison’s grave, how did that fool the coroner? And, perhaps most importantly, did Alison have anything to do with her potential death? Basically, we want to learn everything we can about this missing teen who seems to have some things in common with Ali so we can figure out if she has everything in common with Ali i.e. if she, too, had faked her death. It seems like a bit of a long shot, but you never know with this show. And, the more we learn about the “A” game, the less sure we are about how large this conspiracy runs. Could it have stretched all the way to Cortland? And why hasn’t anyone brought up Sara before?

What we think we know

We  have a great number of theories concerning Sara Harvey. Here are just a few:

  • Alison and Sara met at Radley. Sara could even be “the blond girl” who interacted with Toby’s mom at the mental institution.

  • Alison killed Sara to cover her tracks.

  • “A” killed Sara to send a message to Alison.

  • Sara was on Cape May that summer.

  • Sara is Alison’s twin.

  • We know the boy Sara supposedly ran away with.

We’re not sure how this potential truths could or might fit together, but we hope that Sara’s role in the storyline moving forward is worth the weight of introducing an entirely new character (even if she is off screen). It could be great or it could be one twist too many.

Who do you think Sara Harvey is? And are you excited to explore her part in the “A” game, or does it feel like an unnecessary add-on? Sound off in the comments below!
