If you’ve seen the promo for tonight’s Pretty Little Liars ep (Season 4, Episode 9: “Into the Deep”), then you know Jenna (Tammin Sursok) is not only back, but featured heavily as the Liars press her for answers she - per the usual doesn’t want to give. How did PLL showrunner Marlene King describe Jenna’s turn in the episode?

“Tomorrow @tamminsursok1 is back on PLL. And she will leave u breathless!” tweeted Marlene yesterday, making us seriously excited for Jenna’s return. Jenna may not be the Liars’ BFF, but she always ups the ante when she comes to Rosewood.

It seems like Jenna is not only back, but might just be garnering our sympathy. We know from this tantalizing sneak peek that Jenna wonders if she should have revealed more to the police regarding Alison, is steadily losing her eyesight again, and ominously doesn’t have “much time left.” As terrible as she can be, Jenna has seemingly suffered at the hands of “A” as much as the Liars. It’s not hard to imagine why Tammin’s performance in tonight’s episode might leave us “breathless.”

As close readers of Marlene’s tweets, we also wonder if “breathless” is a more literal clue to Jenna’s fate. In the promo for tonight’s episode, we see Emily find someone floating face-down in a lake. Em seems to think it is Spencer, but what if the floater is actually Jenna? It would certainly fit in well with Jenna’s mention of not having much time left, and give Marlene’s “breathless” comment added meaning...

Are you excited for Jenna/Tammin’s return? Do you think Jenna is the one Emily finds floating in the lake? Sound off in the comments below!
