According to showrunner Marlene King, we will get the answer to at least one mystery surrounding Jenna this season.

As you probably remember, in Season 2, Episode 25: “UnmAsked” Jenna was spotted talking to someone on a park bench. Well, Marlene recently tweeted that we'll find out the identity of that person in the Season 3B finale.

We're excited to learn more about what was going on with Jenna during that episode, especially since Tammin Sursok has hinted that Jenna may know more than we think. We have a feeling that even though she's currently MIA, Jenna is still a big part of the PLL puzzle.

Who do you think Jenna was talking to? Share your theories in the comments below!
