In Emily's bedroom, Spencer is on the phone with Toby and asks him to call her later. After ending the call, Aria asks Spencer what Toby said and she tells the girls that nobody was inside the Cavanaugh house when it exploded, but Toby's dad broke his leg while trying to avoid a falling tree. When Hanna says that it could have been worse, Spencer tells her that Caleb’s with Toby at the hospital. Alison wonders if the text message they received means they were wrong about Shana, and Aria comments that 'A' is alive and knows that she killed Shana. With Emily convinced that Shana was 'A' and therefore couldn't have sent the text, Hanna reminds her they got a text seconds after the house blew up, "either Shana can cause explosions from the grave, or A is back". Spencer says she thinks that 'A' never left, and Aria says that 'A' has been here the whole time, just waiting to resurface. As Alison wonders why 'A' would resurface now, and Spencer says that's what they have to figure out. With the town of Rosewood trying to get back to normal, the PLLs — especially Ali — are far from okay after the latest "accident." Alison is especially spooked and thinking that it wasn't the right decision to come home after all, she starts to consider leaving for good. But Aria, Emily, Hanna and Spencer are determined to keep her safe in Rosewood and to figure out who and what is behind this latest incident. Meanwhile, Caleb also starts second-guessing his return, and Ezra dives into his research to help find answers. #PLL #PrettyLittleLiars
