When Tina is publicly harassed, her mother rushes in, calls the police and demands a public apology. Professor Truman arrives late as they decide to send a lawyer's letter to the attackers. They then go to Dr. Jacob's clinic asking him to treat Tina's illness. Jacob diagnoses a likely familial terminal genetic disease and says curing it requires finding the root cause. He insists they must locate Tina's father to trace that cause. The episode ends with the group forced into a hunt for the father while Tina's treatment remains unresolved.
