We then see Emily packing up her bag at The Brew where Ezra spots her. She congratulates him on the book, but hears the whistling noise from earlier and asks Ezra if he's heard it. He says that it's called whistle tips and that it's a piece that goes in the exhaust pipe of a car to make that high pitched whining noise, causing Emily to ask if that noise is on purpose. Ezra thinks that it's a sad desperate plea for attention.
After the stalker nearly killed Emily, the Liars begin to take the threats more seriously and attempt to keep their mouths shut to prevent any further harm. Caleb must deal with the collateral damage of taking the blame for the leak about Yvonne; Spencer tries to comfort him and get him to tell the truth. Emily goes on a mission to track down the person who came after her. Aria and Ezra move forward with the novel. Meanwhile, Hanna avoids dealing with her personal life. #PLL #PrettyLittleLiars
