5. Along Comes Mary

Alison is released from Welby under the condition that Mary lives with and supervises her. Mary regrets being manipulated by Archer, and while Alison doesn’t trust her estranged aunt, she knows how it feels to need a second chance. The man Spencer met the night of Archer’s death turns out to be the investigation’s lead detective, Marco Furey. The police find Archer’s car at the train station, but the trail doesn’t end there. Someone uses one of Archer’s credit cards to rent a car before heading out west.

It is unknown who the driver is or why they are continuing to fabricate Archer’s movements. Prior to his death, Archer drained the money from all of Alison’s bank accounts, including her shares of The Carissimi Group. Mona analyzes Archer’s burner phone and reads through his texts. The night he took Alison out of Welby, Archer messaged his accomplice to inform them that Alison didn’t kill Charlotte. Aria and Emily investigate an apartment that Archer had been renting in secret. They find a wealth of evidence, most notably a copy of Shakespeare’s Twelfth Night belonging to “Archer Dunhill.” Emily poses as Archer and invites his accomplice to the apartment, but Toby interrupts before the meeting can happen.

Emily oversleeps and misses an important exam, but still receives an excellent grade. A.D. takes credit for the favor. Despite feeling put off by Emily’s distracted behavior, Sabrina happily agrees to a second date. Spencer finds out from Toby that Caleb disappeared on purpose to sort out his thoughts. Hanna asks what she can do to help, and Spencer urges her to consider where her true feelings lie. Aria answers Ezra’s phone when a call mysteriously comes in from Nicole. Ezra is finally in a good place with his grief, so Aria keeps the call a secret.

She also doesn’t mention anything about the situation with Archer. When Ezra proposes, Aria doesn’t know how to respond. A.D. returns Alison’s red jacket with a note exposing her friends for turning her in. The girls suspect that Jenna could be Archer’s accomplice, especially after she extends her stay at The Radley. Jenna and Sara meet and quickly bond over their hatred of the liars. The devilish duo becomes a terrible trio when Noel Kahn enters the picture.
