Lazarus slips away from sickbay and creates a diversion in engineering to acquire dilithium. With the stolen crystals, he beams down to the planet to repair his ship. Kirk follows, but Lazarus activates his time machine just as Kirk tries to stop him. Kirk is teleported to the anti-matter universe, where he meets the Anti-Lazarus. The Anti-Lazarus admits to stealing the Enterprise's dilithium. He informs Kirk that his people believed two universes existed, and when his matter counterpart learned about it, he went insane and became obsessed with destroying him. He tells Kirk that only by destroying the ship with the two Lazaruses inside the dimensional corridor which links the two universes can both universes be saved. Kirk realizes this would trap the two men in the corridor forever.
