S6, E8: After their latest run-in with Charles, tensions are at an all-time high with the PLLs and the town of Rosewood. Aria's big moment of seeing her work displayed in an art gallery is in jeopardy as Ella (recurring guest star HOLLY MARIE COMBS) is determined to keep her safe at home. Hanna is still uncomfortable with the unexpected scholarship money and is determined to give it back, even if that means ruining her chances at going to her school of choice. To top it all off, due to security issues, Rosewood High is considering not letting the PLLs attend prom - the one normal high school rite of passage the girls are looking forward to. Meanwhile, the more Alison learns about her brother, the harder she finds it to connect a deranged murderer to the young blonde-haired boy she sees in the photos and in her memories.
