In the county health department parking lot, Mia, Mom, and John reconstruct Eugene’s Saturday via alarms, texts, Henry’s House logs, and garage notifications. The only gap—between Dad’s pickup at 4:02 p.m. and arriving home at 5:27—aligns with a 4:15 session noted in Anjeli’s lesson log, making her the likely exposure source. They call Shannon, who reports Adam’s phone passcodes were written as clues, including “add all H & add all Q.”

Octavius uploads more pages from Adam’s notebook. Mia finds Experiment #24 dated yesterday but blank, then earlier entries (#1, #6, #11) rating M, J, and a thicker-penned E, which she concludes is Eugene. Notes on #23 (vacation baselines) and a caution about applying findings to family suggest Adam was expanding his experiments while warning against intentional harm.

Shannon’s PI, Tim, reaches Anjeli’s fiancée: Anjeli is Covid-positive from a detention center outbreak and hospitalized; Adam is not at that facility. The fiancée says Anjeli planned to meet Adam and Eugene at the park Sunday to help resolve a conflict but was rushed to the hospital and never made it.

Driven by a need for answers, the family circles the crowded hospital lot holding a sign asking about Anjeli, but no one responds. Mia reframes earlier clues—the yellow heart, sports gear, voicemail—as ordinary therapy artifacts, not signs of an affair.

That night, they strike “Ran away (Anjeli Rapari?)” from Shannon’s possibilities chart. Mia admits she clung to the affair theory as a coping mechanism because anger felt easier than grief; with it gone, the fear that Adam may be dead looms larger.
