At Billy Finney’s house, Jet Mason anxiously monitors Luke Mason’s location through the tracker she planted on him. Jet insists Luke will lead them to his biological father, whom Jet believes is also the person who attacked Jet. Jet and Billy agree to give Luke one hour to move before Jet asks her mother directly who Luke’s father is.

Jet lays out two suspects: Andrew Smith and Chief Lou Jankowski. Jet argues Andrew could have had motive to kill Jet so Luke would inherit Mason Construction, and Andrew’s connection to the North Street site could explain how the killer hid Jet’s phone and the hammer in fresh foundations. Jet then explains why Lou could fit the physical evidence and timing, and why Jet’s mother’s support for Lou as chief may hint at an old relationship. Billy challenges the logic and asks what they would do once they found the man; Jet admits she hasn’t planned beyond forcing a confession.

Preparing for a confrontation, Jet asks for duct tape and gloves. While searching Billy’s closet for the tape, Jet opens Billy’s tool kit and notices the tools are all Coleby-branded, matching the murder weapon’s set. The kit is missing the hammer, and Jet dumps the tools out, frantically searching and confirming it isn’t there.

Jet panics and accuses Billy of killing her, constructing a timeline and motive: the red wig hair could have transferred to Billy at the Halloween Fair, Billy could have learned about the North Street foundations from Sophia, and Billy could have hidden the phone and hammer before returning to “find” Jet. Billy denies it, crying and pleading with Jet to stop, but Jet spirals through possible reasons Billy might have wanted Jet dead.

Jet is suddenly hit by an agonizing neurological episode as the aneurysm worsens; she collapses, screams, and begins seizing. Billy catches Jet, holds her through the seizure, and—desperate to comfort her—sob-wails that Jet solved it and that he did it, even as Jet weakly tells Billy she knows he would never hurt her. As Jet fades in and out, she tells Billy there are letters in her pocket for everyone, insists Billy must read his, and clings to Billy’s presence while Billy promises to finish the investigation for her as Jet’s consciousness slips away again.
