20. Hush, Hush, Sweet Liars

Caleb is careful to think of everything that could possibly go wrong while setting the trap for ‘A’. He builds an electric fence and installs motion-sensing cameras around The Lost Woods Resort. As they write, Ezra comes to terms with the loss of Nicole, and Aria draws upon the feelings she once had for Ezra. Jillian responds to their first draft with a level of excitement Aria has never seen from her boss. Aria and Ezra celebrate with a spontaneous lovemaking session. Sara’s new hotel room is directly above the forgotten section of Radley’s basement.

Toby volunteers to help Spencer investigate, much to the frustration of Yvonne. The pair discovers a secret room in the old sanitarium, as well as the Radley patient file for Charlotte’s biological mother, Mary Drake. Alison begins to see haunting visions of her mother and Detective Wilden. Emily reassures her that the hallucinations are a side effect of her medication, but Alison continues to lose her grip on reality. She voluntarily commits herself to the same psychiatric hospital that facilitated Charlotte’s treatment. It is later revealed to the viewer that Mary Drake and Elliott Rollins were posing as Jessica and Wilden.

Elliott is after the Carissimi Group funds, while Mary is acting out of resentment for Jessica. Veronica’s team celebrates her campaign and makes last-minute calls to voters. To Spencer’s surprise, Mona shows up to offer her support. The poll results are announced, and Veronica is elected one of Pennsylvania’s state senators. Spending time with Caleb reopens Hanna’s emotional wounds. The night their relationship ended, Hanna bailed on plans with Caleb in favor of a work event. She changed her mind, but Caleb was already gone by the time Hanna made it back to their apartment.

Hanna confesses that she still loves Caleb, and the two kiss. Hanna sends ‘A’ her location from inside a boarded up motel room. A dark figure runs through the area and triggers the cameras, but they avoid electrocution. Meanwhile, Hanna has disappeared through a trap door that was hidden underneath the bed. The liars et al. see a Jessica DiLaurentis look-alike when they review Caleb’s security footage. A mass text taking credit for Hanna’s abduction is signed, “A.D.” 'A' ending: A.D. drags Hanna’s unconscious body across the floor of the church bell tower.
