For Pretty Little Liars Jenna Marshall, the phrase 'forgive and forget' isn't even in her vocabulary.

Tammin Sursok's character will make a shocking return in season 7, and the villain will be looking for payback. Five years have come and gone since the Liars last saw their teenaged foe at the Ice Ball, but Jenna's anger won't have even begun to thaw in the interim.

"You see throughout the other seasons how the girls have actually affected her and her life, and how she was the victim for a long time," Sursok told Teen Vogue. "In Season 7, it's payback. ... She now has a sense of herself. She's done. She knows herself, and it's time to fight for who she is."

In other words, don't expect Jenna's appearance to be a one off. Pretty Little Liars' Marlene King wove a tangled web over the last six seasons, and the showrunner is finally ready to pull all the threads into a nice little bow. As it turns out, Jenna's storyline bears far more weight than we originally expected. Not only will you find out what ol' Sunglasses has been up to, but her return will open the door for a slew of new questions.

"You do get a lot of answers, but you also get a lot of questions," the actress teased. "But you'll definitely find out what's been happening, and she is heavily, heavily, heavily involved with the Liars in the upcoming storyline."

Catch up with Ali (Sasha Pieterse), Emily (Shay Mitchell), Spencer (Troian Bellisario), Aria (Lucy Hale), and Hanna (Ashley Benson) when Pretty Little Liars kicks off the summer season with "Tick Tock, Bitches."

"The PLLs are racing against the clock to save one of their own," Freeform teased. "The only way to do this is by handing over evidence of Charlotte s murderer to Uber A."
