As they arrive at X-18999, Heero and Duo are met by Wufei and Trowa, who fire at them. It soon becomes evident that they were faking things only to make it easier for his friends to infiltrate the colony. Meanwhile, Mariemaia declares war on the ESUN and departs for Earth with Relena. At the same time, a lone MS, piloted by Zechs Merquise, now a ESUN agent, approaches the asteroid MO-III, where Mariemaia's forces prepare themselves for their impending assault on Earth and threatens to blow it to pieces. Dekim's only answer is that if Zechs so much as sneezes, he will drop the asteroid on Earth.
