Three months have passed since Adam’s disappearance. Eugene has been attending group sessions at Anjeli’s; he and other nonverbal patients have composed a group poem with the refrain “I am here” (355). The family is unable to discern whether Adam had cancer, or what the last HQ experiment was.

Mia still feels uneasy, wondering whether Eugene just repeated her speculations about Adam’s death with John. Having found a page from Adam’s folder on the copier tray, she wonders whether it had been used for tracing and whether Hannah and John fabricated the two-page note that exonerates Eugene and corroborates his story. Mia is also suspicious of Eugene’s use of abbreviation, since Anjeli mentioned him being a perfectionist with spelling.

Mia figures out Adam’s phone password, and considers unlocking it to find out definitively about the note (which Eugene said Adam photographed); however, with the last password attempt, she decides to enter a wrong digit, and the phone deletes its data.

On the 100th day after Adam’s disappearance, the family prepares for a ceremony at the waterfall. Mia arrives early to burn the account she’s written of what has happened to her family, including all her “ugly thoughts” (370).
