A Space Oddity - S4.E22

Because of a surprise dorm inspection, Odd has to convince Yumi to keep Kiwi at her house. Jeremie, meanwhile, has located the next Replika, a copy of Sector Five. Its supercomputer is located on a newly-built space station orbiting Earth. While Odd and Yumi work to disable it, Aelita and Ulrich work to disable the Replika's defenses of Sector Five, which threaten to destroy the Skid. To make matters worse, the supercomputer is guarded by a trio of floating spheres that can grow spikes and melt through metal. In the end, Odd disables the supercomputer by breaking some cooling pipes in the room and damaging it with water. All the while, Yumi's dad, Takeo, has been having fun with Kiwi, much to Odd and Yumi's surprise.
