Two months after Hawaii, Maddy gets a letter from the doctor who treated her when she got sick there, and in the note, the doctor says she thinks that Maddy does not have SCID, and she got sick because she had spent her whole life inside and has never formed a natural immunity. The doctor blames myocarditis as the reason for Maddy's heart-stopping. Maddy, angry and panicked, searches her mother's medical files but does not find the test results or doctor's notes that would confirm she had SCID.
