the shower. Meanwhile, Aria reveals her condition to Ezra. In the jail, Spencer visits Mary and asks her for help. Later, in Aria's rehearsal dinner, Hanna takes Mona with her, and the Liars — and Hanna's mother — condemn it. Hanna manages to convince her friends to give Mona a chance. Ezra and Byron talk about Ezra's marriage with Aria, and Byron gives him his blessing. Later, Alison proposes to Emily who accepts. Spencer shows up at Toby's room at the Radley and they have sex. Right after, she is at the Barn and is knocked down by Mona. She then wakes up on the floor of a modern strange room which resembles the one from "Game Over, Charles". She looks at herself in a supposed mirror and puts her hand on her head. However, her "reflection" lifts down her hand and scares her, revealing that it is not a mirror. Mary Drake then appears and injects a sedative into Spencer, while she looks on in shock at the woman who looks exactly like her. Spencer soon awakens and comes face to face with her long lost identical twin sister named Alex Drake who is also revealed to be their tormentor known as "A.D." and the third daughter of Mary Drake who was sold by their mother in order to fund her release from Radley. She lived in London on the streets where she came across Wren Kingston whom she dated and learned about her twin sister and her family. She soon met her half sister Charlotte and the two instantly connected as well as befriending Archer Dunhill who had met Charlotte on the plane after she left Rosewood to get away from being arrested for killing Wilden.

She also posed as Spencer multiple times when she kissed Toby in "The Darkest Knight" and had sex with him in "Choose or Lose" and appeared to Hanna when she was being held by Alex in her dream sequence for confessing to killing Charlotte. Alex also shot Spencer in the blind school and got Wren to shoot her in the shoulder so she would be like her twin sister and soon re-formed the A Team, now consisting of Jenna,
