Facing public backlash after repeated delays, the Lowe Group's anti-cancer drug LuckyOne stalls when test pills show little effect. Researchers privately contact Carolyn — the mysterious, legendary physician known as the Green Wanderer who previously guided LuckyOne — and ask her to help Frazier, a scientist who has struggled for three years and whose father died of cancer. Carolyn agrees and vows to solve the drug's problems. The episode closes as Beacon Hospital and company staff recognize her identity and call out, "Green Wanderer?!", leaving her move from secrecy into the spotlight unresolved.
