The previous episode of Pretty Little Liars Season 7 saw Hanna become increasingly convinced that Noel Kahn is Mary Drake's second child, and even more frustrated when her friends don't feel the same way. Pretty Little Liars Season 7 Episode 8 ended with Hanna going rogue to catch Noel herself. "The Wrath of Kahn" begins with Aria questioning Hanna's text that says she went to New York for a few days for business with Lucas. Emily tries to call Hanna to tell her to come back to Rosewood, but Hanna doesn't answer; she's too busy setting things up for her secret plan. Marco stops by Spencer's house to say hi after visiting Alison and reveals that they tracked Archer to France. The case is now out of his jurisdiction since Archer is overseas, which means Marco can now take Spencer out on a date without things being complicated. Spencer states that she's just coming out of a relationship and it's too soon to start dating again.
Jason catches Aria on her way to the courthouse to ask about the fire at his Aunt Carol's house. At first Aria denies knowing about it, but she eventually tells Jason what the PLLs discovered regarding his mom and Mary's second child. Jason goes with Aria to the court house since he's a relative of Mary and will more likely be able to get information over Aria. While Jason and Aria are waiting at the courthouse we see a flashback of their fling during the five missing years, and it turns out that Jason even asked Aria to come to Ethiopia with him. The Pretty Little Liars Episode 9 trailer worried us that Aria would cheat on Ezra with Jason, but we were relieved to find out that it's a scene from the past. Back in the present day Aria expresses to Jason her anxiety about Nicole still being alive and if that will change her relationship with Ezra, but Jason comforts Aria by saying that she and Ezra have always been meant for each other.
Hanna follows Noel Kahn and watches him throw a trash bag into a dumpster. After he leaves Hanna looks inside the bag and finds Sara Harvey's phone. She texts Noel from an anonymous number saying that she has Sara's phone and to come meet her at a bar. Hanna puts a sleeping pill in the beer she offers to Noel, but he doesn't fall for her trick. Instead Noel takes the phone and threatens that Hanna will end up just like Sara if she isn't careful. Emily has her interview for head swim coach at Rosewood High, where she sees Paige who is also interviewing for the position. Paige asks Emily to hangout afterwards, but Emily says that she'll probably be with Sabrina. Emily admits that she doesn't think it will last with Sabrina because she can't talk to her about her past, or present. Emily then reveals to Paige that she's getting tormented by a mysterious person again. Paige is obviously concerned for Emily, but encourages her to try to include Sabrina in all aspects of her life.
Spencer uses her sleuthing skills to find out Noel's address, which happens to be near to where Hanna was held hostage. Emily and Spencer break into Noel's house and search for anything suspicious. They find a flash drive that shows Noel was Charlotte's accomplice when the PLLs were locked in the Dollhouse. Emily talks to Lucas and tells Spencer and Aria that Hanna isn't with him, and they realise that she's probably off somewhere trying to catch Noel Kahn. After her plan goes south Hanna listens to Emily's voicemail, which says that they believe her about Noel and want to go to the police all together.
Spencer goes home and watches a video of herself from the flash drive, which prompts her to leave Marco a message asking him to come over. The power goes out because of a storm, which also causes a tree branch to crash through Spencer's kitchen window. Spencer sees the shadow of a hooded figure on her wall, and luckily Marco shows up just in time to search the house for her. While Marco checks for an intruder, Spencer notices that the flash drive is missing. She then asks him to stay for a bit since she doesn't want to be alone.
Meanwhile Emily calls Paige to talk about her problems instead of confiding in Sabrina. Ezra tells Aria that Nicole wasn't one of the hostages in Colombia so he's returning to Rosewood. Aria and Jason receive a fax about the adoption of Mary's second child from the courthouse, but since it was a closed adoption all the relevant info is blacked out. The only useful thing is that Noel Kahn's father was the judge who presided over the case, and Aria believes that the Kahns adopted the baby. The episode ends with Hanna sneaking up behind Noel and hitting him across the head with a baseball bat. Hanna clearly isn't ready to give up on her plans that easily! Do you think that Noel is Mary's second child?
