Duncan pilots a very small aircraft with Aria sitting next to him in the cockpit. They look down at Pennsylvania, all lit up below them. Aria asks how often he would take Ali flying. He says as often as he could. Guessing Aria's next question, he says he could have been in love with Ali had someone, another boy, not gotten in the way. Duncan says flying made Alison feel safe and in control. He tells Aria to take the yoke, which controls the plane. When she declines, he tells her she will never understand her friend if she doesn't try. Aria takes hold, and Duncan lets go. He says Alison's face would change when she was up there, and no one could get to her. He didn't know who was after her - a stranger, a boy she knew, or a friend. The plane shakes and Aria wants to let go, but Duncan makes her hold on. He asks why Aria said they never caught Ali's killer if Ian Thomas confessed in his suicide note. Aria discloses that she and her friends think the note was fake and Ian was protecting someone. Duncan finally takes back control of the plane and reveals he picked up Alison from Hilton Head Sunday morning of Labor Day weekend and flew her to Philadelphia. He said she was different that day; she figured something out. Aria realizes Ali was in town 6 or 7 hours earlier than they previously thought.
The liars are on the quest for answers of what Alison knew before she died; Jason drops off a bag of Alison's personal items that could be more than just a bag of junk; Toby's return to Rosewood brings a surprise reunion that ends dangerously. #PLL #PrettyLittleLiars
