Walking into her bedroom to grab a few school books, Spencer turns around to find Peter standing in her doorway. Surprised, Spencer says she didn't see his car in the driveway, and Peter tells her it's in a garage. When Spencer asks why he isn't at work, Peter says that it's a little hard to concentrate when his wife and daughter are living at a hotel. Telling him that she has class in ten minutes, Spencer tries to walk past him, but Peter blocks her and asks her what is going on. Spencer tells him he'll have to discuss that with Veronica. Spencer tells him that they know that he lied about his and Melissa’s whereabouts the night Jessica DiLaurentis died. Spencer asks him what will he do when the cops find out that the pills that were used to kill Jessica was in Peter’s medicine cabinet. Peter tells Spencer that he did not kill Jessica. Spencer says that she knows he was just trying to protect her. He is adamant he'd never take anybody's life to cover up for Spencer. Spencer demands to know where Melissa and Peter was that night.

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
