Rosamia refuses to see the doctor until Shinta and Qum convince her by example that there's nothing to fear.
Aboard the Dogoth Gear, Basque orders Reccoa to prove her new loyalties by leading an attack on Bunch 21 (Side 2).
Reccoa's Messala and the pair of Hizacks with the G-3 nerve gas bomb are detected by the colony and intercepted by a squad of Nemos. Camille in Z-Gundam and Emma in the Mark-II take off to join them, but Quattro stays behind to keep an eye on Rozamia.
Using the children as a diversion, Rosamia takes a Nemo (which she derisively calls "A simple machine!") and chases after her "brother" with Quattro close behind in the Type-100.
Meanwhile, the G-3 is released into Bunch 21 with deadly effect. Camille senses the deaths of the eight million inhabitants.
Battle is joined. Camille sees Reccoa in the Messala, but is accosted by Rosamia before he can confront her. Camille and Rosamia enter Bunch 21 through a breach in the hull. Rosamia witnesses the mass murder as Camille exacts a measure of revenge by blasting the Hizacks. Quattro confronts Reccoa, but can't bring himself to stop her.
Rosamia, like Four, falls victim to her programming and suddenly sees Camille as the Enemy. Emma keeps Rosamia from killing Camille, who stops Emma from killing Rosamia. Reccoa and Rosamia escape, leaving Camille and Quattro to reflect on the consequences of their actions.
バスクは毒ガス作戦の指揮をレコアに任せる。ティターンズへの忠誠を試すのが目的だ。それを阻止する作戦中、ロザミィもアーガマからネモで飛び出した。それは彼女が自分の使命が打倒Zであることに気付いた瞬間だった。
Rosamia se niega a ver al médico hasta que Shinta y Qum la convencen con el ejemplo de que no hay nada que temer. A bordo del Dogoth Gear, Basque le ordena a Reccoa que demuestre sus nuevas lealtades liderando un ataque contra el Grupo 21 (Lado 2). El Messala de Reccoa y el par de Hizacks con la bomba de gas nervioso G-3 son detectados por la colonia e interceptados por un escuadrón de Nemos. Camille en Z-Gundam y Emma en el Mark-II despegan para unirse a ellos, pero Quattro se queda atrás para vigilar a Rozamia. Usando a los niños como diversión, Rosamia toma un Nemo (que ella llama burlonamente "¡Una máquina simple!") Y persigue a su "hermano" con Quattro detrás en el Tipo-100. Mientras tanto, el G-3 se libera en Bunch 21 con un efecto mortal. Camille siente la muerte de los ocho millones de habitantes. La batalla está unida.
