'Pretty Little Liars' season 7 episode 9 spoilers, plot news: Hanna reveals Uber A's true identity; Emily turns to Paige for comfort

One of the Liars will go rogue in the upcoming episode of Freeform's mystery thriller drama "Pretty Little Liars" season 7.
When the typical methods of investigating are not working anymore, one of the girls will do the unthinkable and take matters into her own hands. According to the official synopsis for next week's episode titled "The Wrath of Kahn," one of the PLLs will go to extremes just to prove that Noel Kahn (Brant Daugherty) and Uber A are the same person. While still worrying about her emotional state, the rest of the girls attempt to find more evidence to support her theory. In an unexpected turn of events, Emily (Shay Mitchell) turns to her former love interest Paige (Lindsey Shaw) to seek comfort — leading to some tension in her other relationships. Jason (Drew Van Acker) and Aria (Lucy Hale) will team up to gather information about Mary's (Andrea Parker) past she may be hiding.
The promo clip for episode 9 has been released, hinting that something terrible will happen. After finding out that Noel is Uber A, Hanna (Ashley Benson) makes a video letting everyone know something she discovered that puts her life in danger. "My name is Hanna Marin," she says. "If you find this video before I finish what I need to do, something went terribly wrong."
Hanna confronts Noel, telling him she knows he killed Sara (Dre Davis). Later, Noel warns Hanna to stay off his business if she doesn't want to end up dead. The next scene cuts to Emily telling Paige "It's happening again." While Spencer (Troian Bellisario) is looking at a video on her computer, an unknown man forces his way into her house and threatens to hurt her."It's over," Hanna says while talking to another unknown character before the clip ends.
