S4·E16 A Lack of Goodwill

Jeremy has developed a program to make the William clone smarter, but the learning curve is still problematic, as it tries to fling a glass into the air from a fork. Milly and Tamiya, overhearing the group's conversation about the clone, decide to ask him personally. The clone, having never been told to keep the information a secret, reveals everything to them, and even takes them to the factory. Meanwhile, Jeremy plans a mission to the next Replika, a copy of the Desert Sector. During the trip, William emerges from a scanner and tries to destroy the supercomputer. With the help of Milly, Tamiya, and the William clone, he is defeated, and a return trip keeps Milly and Tamiya in the dark about the Supercomputer.
