Hanna is in her kitchen looking at the Harwich University site on her laptop, and discovers that Lesli is a teaching assistant in her science department. She then sends Emily a text letting her know what she found out. Caleb shows up at the Marin household and Ashley invites him in for breakfast; he greets Hanna who acts dismissive towards him. He sees a lump on her neck and asks what it is, prompting Hanna to say that she just woke up. Hanna tells her mom that she won't be staying for breakfast because she has to meet Spencer for Spencer's appointment in Philly and tells Caleb she'll call him later.
With all signs pointing to Lesli as the tormentor in the hoodie, the PLLs are on a mission to get concrete proof before bringing their findings to the police but as the girls ramp up their investigation, threats from “A” escalate. Meanwhile, a friend of Emily’s makes her a surprising offer, and Spencer is pressured by her family to make an important decision. #PLL #PrettyLittleLiars
