2x12 - Space Brothers

The AsCans begin their flight studies, in which they must learn three weeks worth of flight knowledge in three days. Meanwhile, Sharon speaks with Daniel Morrison, a university lecturer from Hawaii, who expresses his interest in her telescope proposal and offers his support. She eventually arrives in Houston where she meets up with Hibito, who senses some limpness in her hands. After Sharon falls over whilst trying to carry some drinks, her assistant and Hibito check her into a medical center, where the doctor claims she is only feeling fatigue. Later that night, Hibito and Sharon head to a party Mutta and the others are holding. When Serika notices Sharon's battered cellphone, she is reminded of when her father was first diagnosed with his illness and discovers Sharon is showing the same symptons he had.
