S1, E12: Hanna's return home from the hospital should be a joyous event, but being stuck in a wheelchair and feeling haunted by "A" makes her return feel more like a Hitchcock nightmare than a proper homecoming. Even though the girls try their best to support Hanna, they all have troubles they must face as well: Spencer is still reeling from Melissa's (recurring guest star Torrey DeVitto – One Tree Hill) surprise, when an unexpected roadblock is thrown up in her relationship with Alex (recurring guest star Diego Boneta – 90210, Mean Girls 2); Emily is hoping that an introduction to Maya during a tense family meal will smooth whatever apprehensions her parents may have; and blackmail is in the air as Aria and Ezra suspect a student is on to them.
