Jet Mason is processed at the police station—mugshots, fingerprints, repeated searches—before being cuffed in an interview room with the chief and Sergeant Jack Finney. Jet insists she did not burn down Mason Construction and begs to be released because she is dying, but the chief treats the arson as a major felony and focuses on proving Jet lied about her Wednesday-night alibi.

The chief presents a time-stamped photo of Jet’s truck parked near Mason Construction at 11:22 p.m., minutes after the alarm triggered and before the fire department arrived. Jet challenges who took the photo and is told it was a “witness” who received an alarm alert and went to investigate. Jet realizes the witness must be Luke Mason, meaning Luke was likely already there, set the fire, and is now framing Jet; Jet erupts in rage, certain Luke is trying to steal her remaining time by getting her jailed.

Under pressure to explain why she was there, Jet refuses to implicate Billy Finney and fabricates a story that she and Billy were having sex in the truck and left when they heard sirens. The chief still claims Jet did it; Jack admits they lack proof Jet entered the building but says a warrant has been issued and Jet can be held up to forty-eight hours, leaving Jet terrified she will die in custody before she can finish her investigation or say goodbye.

In the holding cell, Jet spirals through unresolved questions and grief, especially that Billy may hate her. JJ is marched past on the way to be charged; he insists he did not attack Jet and apologizes for the loan, and when Jet asks, JJ denies grabbing Jet’s arm at the fair while wearing a red wig, deepening Jet’s belief someone else is responsible.

Mr Finney allows Jet her one phone call and urges her to call her father for a lawyer, but Jet chooses to call Billy instead. Billy does not answer, so Jet leaves a voicemail apologizing for coercing the grade change that hurt Beth, admitting her lifelong obsession with proving herself, and telling Billy he made her feel alive in her final week. Back in the cell, Jet asks Mr Finney for paper and a pen to write goodbye letters; with her injured right arm unusable, she begins a slow, shaky letter to her mother in red ink.
