Rosewood is a revolving door for murders, kidnappers, and possible 'A' suspects. Just as we finally said goodbye to evil Doctor Rollins, in comes Jenna Marshall who we haven't seen since Season 5. It seems the Liars just can't catch break (when could they ever?). With Jenna back in town this can only mean trouble for the Liars. Jenna has been a constant thorn in the Liars side since Season 1, but to be fair they are the reason why she's blind. Of course, Jenna would hate them. Who wouldn't? But why is Jenna back really? Thankfully fans are already on the case and there's plenty of Jenna Pretty Little Liars theories in the works.
Did Jenna kill Charlotte? Is Jenna A.D.? Does Jenna somehow know about the Liars killing Dr. Rollins? And most importantly, why has she decided to return to Rosewood now after all this time? There's so many theories to consider and really any of them of could be true. One can never be certain what PLL showrunner, I. Marlene King, has up her sleeve but by now fans have come to expect the unexpected. Here's just a few Jenna theories that seem just far fetched enough to be plausible.
