On this week's Pretty Little Liars, Spencer's rehab battle has only just begun.

Her parents put her on heavy restriction and hire a drug and alcohol counselor to help her recovery. Irritated by her folks and Dean, Spencer is equally troubled by possible memories of the night Alison died.

As Spencer begins to suspect that she may have buried Alison, A starts to torment her about it as well.

Meanwhile, Hanna gets closer to Travis, but she ends up distracted during their dinner because of Paige's note to Detective Holbrook. Holbrook thinks Hanna has something to do it and begins questioning Mrs. DiLaurentis.

Emily confronts Mona about her relationships with both Ezra and Mike, but she doesn't find out much about Ezra's research. Aria, however, does get Ezra's manuscript and finds out that he suspected Mrs. DiLaurentis was A.
