Lois tells Clark she already realized that he is Superman. In a moment after the surprise, Lois and Clark have an arguement. She is mad at Clark because he didn't tell her his identity secret, and he gets mad at her because she's not sure yet about marriage and declined his proposal. Bill Church, now married with his nurse Mindy, wants to be a "good guy" and creates a security team to fight against the crime in Metropolis, but his wife and his son think he lost his mind. Martha tells Lois and Jonathan tells Clark the problems that they had before their marriage. Bill Jr. and Mindy succeed on their plan to put Bill Church on jail, (yeah, his own father..) but, in the time the police arrests Bill, they arrest Bill Jr. too. Mindy Church is now the head of the Intergang. Lois and Clark decide to wait more time until get married.
