Jenna returns from having eye surgery and Toby, now cold and distant to the Little Liars (especially Spencer!), has become her guardian as she heals.
The Little Liars are hot on "A's" trail as they try to dissect Ali's final days. While Spencer and Emily are going through a bag of Ali's old things that Jason gave them, Aria is getting information from Duncan, an old friend of Ali's. Thinking the bag holds no answers, the Liars return it to the DiLaurentis house. But when they decide they want it back to do more investigating, they return and find the house up in flames -- with Jenna inside! Hanna pulls her out of the house and saves her life.
Meanwhile, Ezra stands up to Byron. Toby has a run in with Wren. And Emily admits to Maya's parents that she's heard from Maya since she left Rosewood.
