The family escorts Eugene to the juvenile detention center, where they wait outside as Detective Janus seeks paperwork. While they sit under a willow tree, Mia watches Eugene soak in a favorite video and glimpses a blank-faced teen behind barred windows, deepening her dread of leaving Eugene there.

Shannon returns with news of a sudden Covid lockdown: the facility cannot admit anyone. After calls to Officer Higashida, Eugene is ordered to house arrest rather than detention. The family feels overwhelming relief as they walk back to the station, though Mia is jolted by guilt when reminded of a new ATM hit and the video search tied to Adam’s card.

In a conference room, Mia decides to reveal everything: the blood under Eugene’s nails, the shirt she washed, the insurance file she found, Kenny’s screenshot, Detective Janus’s visit to the mommy‑blogger neighbor, and Adam’s HQ notebook of experiments, including an entry dated the day before. She and John also tell Mom about indications of Adam’s cancer. Shannon redirects them to Friday’s hearing and the stakes: if prosecutors tie Eugene to Adam’s disappearance, a manslaughter theory could drive detention or inpatient placement despite incompetency or disability defenses.

Shannon presents a chart of possible explanations for Adam’s disappearance, crossing off miscommunication, lost/injured, and kidnapping, while prioritizing leads such as running off with a woman, suicide (if cancer is confirmed), accidental drowning, and hiding for an experiment. She floats a life‑insurance scenario involving staged accidental death to secure a double payout. John rejects this as out of character, but Shannon stresses persuading outsiders to accept non‑Eugene explanations. She assigns tasks—contact the oncologist, reach Adam’s friends, find Anjeli, access Adam’s devices, interview the neighbor, and get Eugene evaluated—setting a 50‑hour push to keep Eugene at home through the hearing.
