Cooper brings MIKE to the Great Northern and gathers guests and staff before him, hoping he can recognise BOB's human host. The search is interrupted when Ben enters and MIKE collapses. Hawk goes to Harold's home and finds him dead, with Laura's secret diary torn apart. Its surviving entries describe BOB's abuse and threaten to expose Ben. Audrey adds that Ben slept with Laura and owned One Eyed Jacks, strengthening the officers' suspicions. They arrest Ben while he is arranging his deal with Tojamura. Elsewhere, Bobby discovers a recording hidden in Leo's boot, and Catherine reveals to Pete that she is alive beneath Tojamura's disguise.
Maddy tells the Palmers that she is ready to return home. Sarah later struggles downstairs and sees a white horse before collapsing. Leland adjusts his tie in a mirror, where BOB looks back, revealing the connection the investigators have not yet understood. At the Roadhouse, Cooper sees the Giant warning that the violence is happening again. Back in the Palmer house, Leland and BOB appear in alternating images as Maddy is beaten and killed. Her hope of leaving Twin Peaks ends inside the home where she came to support her family. The Roadhouse falls into an unexplained sadness, with Donna crying and Cooper sensing disaster without knowing who has suffered.
