Synopsis:
Superman and Supergirl have been tasked with the destruction of a collection of super-weapons. They take the weapons to the Fortress of Solitude to dispose of them in a disintegration pit filled with Kryptonian elements. When a brainwash bomb is thrown into the pit it releases an invisible gas which cause both Kryptonians to hate one another. Supergirl constructs a barrier that divides the Fortress in two. Superman begins destroying Supergirl's trophies and mementos. Eventually, Superman is tipped off to the presence of the gas when he sees the two heads of a siamese bird quarreling. He lures Supergirl outside. In the fresh air, both regain their senses ending their feud.
