Pretty Little Liars' on-again off-again couple might become on-again very soon.

Fan-favorites Aria (Lucy Hale) and Ezra (Ian Harding), the only romantic relationship that has spanned the length of the series, have had more hurdles to overcome than most couples twice their age. First, there was the fact that Ezra was Aria's high school teacher. Then, Aria's nemesis A set out to break the couple up many times. And most recently, Ezra learned he had a son with Maggie (Larisa Oleynick), an ex who came to live with Ezra in Rosewood. But just when Aria may have finally moved on from her first love, Hale says Ezra might be back in her life before the season's end.

"For the first time, [Aria] likes a guy other than Ezra and wants to make it work," Hale tells "But I think Aria always senses it's just not the same. There's always that one person. Now [Maggie], who ruined her relationship, might be leaving, so she sees the light at the end of the tunnel."

On Tuesday's episode — which Hale tells us was her favorite ever to film — Aria and her new beau Jake (Ryan Guzman) attend the school's hoedown. Although their relationship is progressing, Aria is stopped in her tracks by Ezra. "Ezra is dealing with a lot and he starts to reach out to her for help with what he's going through," Hale says. "When Ezra reaches out she's like, 'Oh sh--, I'm still in love with you.'"

But before Aria can truly confront her feelings, she has something bigger to worry about: A and the mysterious Red Coat. During next week's summer finale, Aria joins Spencer (Troian Bellisario), Emily (Shay Mitchell) and Hanna (Ashley Benson) as they head to Ravenswood to track down more clues.

"In Ravenswood, they're on the lookout for this magician who they think is a clue that will lead them to Ali [Sasha Pieterse] who at this point they think is alive," Hale says. There, Aria may go missing [after] she's lured into this magic trick. A funny line from the episode is, 'No, trust me, I don't do boxes,' in reference to the last Halloween episode."

And despite another terrifying situation for Aria, Hale says the episode provides many answers for the girls — and, of course, the audience. "We reveal who Red Coat is," Hale says. "Whoever Red Coat is, whoever A is, he or she doesn't like to be messed with. Once we one-up him or her and play along with the game, what's freaking he or she out is that we're playing the game, and we're playing it right."
