13. Grave New World

Aria, Emily, Hanna, and Spencer crash the Ravenswood Founders Day Celebration following the revelation that Alison could be alive. Ezra is also there and is seen dressed in a World War I era soldiers uniform. The girls see Red Coat and attempt to follow her but she escapes before they can get to her. Caleb arrives in Ravenswood and meets Miranda and they bond. Hanna becomes separated from the rest of the Liars and finds herself trapped in a phone booth where she sees Alison through the glass before she is attacked by "A".

Spencer is also attacked in a greenhouse by Ezra, who is dressed in his World War I uniform, where she cuts his hand. Mrs. Grunwald tells the girls that one of them has been touched by the one Alison fears the most. This would suggest that Beach Hottie, aka Board Shorts, attacked Spencer and Alison. Caleb decides to stay in Ravenswood after he finds his and Miranda's names and photos on graves. Spencer's tires are slashed and Ezra suspiciously picks the Liars up. Once back in Rosewood, the Liars see Red Coat again and follow her to Spencer's back yard where she takes off her hood.

It's Alison, alive and well. She tells them she still can't come back to Rosewood because it's not safe. Ezra turns up with Aria's phone and when they turn back around Alison has gone. The Liars are perplexed by Alison's disappearance yet again. This episode also serves as a backdoor pilot of the series’s spinoff Ravenswood.
