We knew that Jenna Marshall (Tammin Sursok) would be returning to Pretty Little Liars in the 100th episode, but now we have the photo evidence! Check out the snapshot of Jenna back in action.

“#pll #set #jenna #isitsunnyout?” Tammin captioned the photo of herself hanging on the set of Pretty Little Liars — with sunglasses, of course. Finally! It’s been far too long since we’ve seen this character causing the Liars anxiety. And are we to infer from Tammin’s sunglass comment that Jenna has completely lost her eyesight again? She tends to wear the shades when she can’t see, and we know that the surgery that restored her eyesight was proving itself temporary. Poor Jenna!

You know what this means, right? This means that we will probably, hopefully get some interaction between Jenna and Alison (Sasha Pieterse) in the 100th episode, as Ali is returning to Rosewood in Season 5. We’re anxious to see how these two characters interact given that they were such straight-up enemies before. Will their respective journeys since Ali’s disappearance change their relationship to one another? We can’t imagine Jenna has forgiven Ali for blinding her, especially since she has an all-too-present reminder of Ali’s actions with the presumed re-loss of her eyesight. Ali, on the other hand, will hopefully have gained some perspective on just how damaging her games were to Jenna.

Are you excited to see Jenna again? How do you think her reunion with Ali might go? Share your theories in the comments below!
