The Eternal Flame of the Shooting Stars
The Romefeller launch operation Nova, a mission to send down mobile dolls to earth and conquer resisting countries. Pro-Treize soldiers intercepts an attack at their base, but finds the mobile dolls to be nearly impossible to beat. The narration tells that one man within the foundation is against the use of mobile dolls - Treize Khushrenada. He wishes to break free from the foundation, but it places him under arrest. However, pro-Treize soldiers break away from OZ, and form their own faction.
Dermail explains that these pro-Treize OZ forces is causing more trouble than needed, and that he'll need more mobile dolls soon. Tsubarov says that won't be a problem, everything is the same in space. They have even captured the new Gundam and its pilot, and will destroy it on the moon base, as it can be used as a symbol of resistance otherwise. Tsubarov reflects to himself that he thinks killing all who oppose them is the best way of dealing with things.
At a hangar, the wrecked Mercurius and Vayeate are brought in, as well as the new Gundam. Quatre and Heero are handcuffed, and being taken away, as Quatre suddenly sees Trowa's mobile suit. He breaks free from the guards, and ignores that they're firing at him, to get close to the mobile suit. Once there, he falls down on his knees and sobs, begging Trowa to forgive him. At that point, the OZ soldiers get he new orders from Tsubarov that the Gundam pilots are to be executed at once. As they're about to shoot Quatre and Heero, pro-Treize soldiers appear and makes the OZ surrender.
Trant tests the cockpit system of the new Gundam, as he gets a call from Tsubarov. Excitedly, he tells Tsubarov about their tests, that the pilot of the Gundam gets faster reaction times by the system, and that he becomes even better than the mobile dolls. Tsubarov isn't pleased to hear this, and orders the Gundam to be destroyed. Afterwards, Trant decides to break orders, and do some more testing of the system.
Quatre and Heero are taken to the Gundam scientists, where they run some test on Quatre to find out how he was affected by the Gundam. Nothing wrong shows up on the scans. Dr. J and professor G briefs Heero about the current situation - Treize is arrested, OZ has been divided in two parts, Lady Une might be dead, and Duo and Wufei have escaped from the prison. When asked what happened to Trowa, they say that since his mobile suit was destroyed, he's been reported missing, and is presumed dead. It's sad that their group has been dimished, but that's that.
As they proceed to brief Heero on the pro-Treize forces, Quatre interferes, asking them why they don't go search for Trowa. Quatre says he's sure Trowa is alive, and that there are many colonies in the area. The professors look at him oddly, and says that's a problem with him as a soldier... Quatre sags, as they don't even give him an answer. The other scientists says that this is why they took the Gundam, because they were both immature as soldiers, they ended up fighting each other. It would've been better if the pilot had his mind focused on the OZ rather than anything else. To be able to survive in an age with mobile dolls, Quatre must become a perfect soldier. They also say it's ok to go insane, because this is what it's all about.
Heero and Quatre talk about the new Gundam, and Heero wants to know if Quatre knew about the new ZERO system that was installed into it. Quatre says he didn't know, that he focused on the beam cannon instead. Quatre is confused about the fighting, who's enemy and who's friend now? Heero says it's easy, those who try and kill him are his enemies. Quatre questions this, what if they make a mistake? Heero replies with that they're not the ones making mistakes, this whole war is crazy.
The pro-Treize soldiers are discovered by OZ forces, and a battle begins. The pro-Treize faction is soon surrounded and OZ demands that the Gundam pilot is handed over for testing with the new Gundam. The scientists and pro-Treize surrender, stating that it doesn't matter, they've survived longer than expected.
Testing on Heero in the ZERO system begins. As the results come through, Quatre realise that this cockpit system can beat the mobile dolls. Humans are no longer needed in war. Quatre understands that this Gundam is a mistake. The ZERO system slowly but inevitably takes control over Heero, who goes temporarily insane. He starts a battle against OZ suits in the hangar they're in. Heero means that those who try and kill him are his enemies, and those who play with his life is that as well. Images of the professors appear in front of his eyes...
In an adjacent room, the soldiers guarding the professors suddenly run out of the room. Dr. J realise that Heero now must have aquired his target - the OZ and themselves. As no one make sure they stay where they should, the professors simply walks out of the room.
Trant gets reports of what happened, and his subordinates want to know if they should request backup from Tsubarov. Trant says he couldn't possibl explain this mishap to Tsubarov. Suddenly, Quatre runs for a mobile suit in their hangar, and jumps into it, despite OZs protests. He means he's the only one who can stop Heero. Quatre tells them that Trowa warned him of this, there's no use fighting alone.
Quatre encounters Heero in another hangar with his mobile suit. Quatre tries to talk Heero out of it, explaing what the system does - he gains better reflexes, but there's a price for that, as the pilot loses something in return. He tells Heero that he lost the most important thing about himself in that damned system, and he doesn't want Heero to lose it as well. They argue a bit, before Heero attacks Quatre. Quatre warns Heero, if he doesn't stop fighting now, he'll blow them both up with the self destruct device. As things look really bad for Quatre, he tells Heero what Trowa told him before, that they are no longer needed in space. Heero eventually snaps out of the ZERO system's control, and Quatre tells him they shouldn't fight each other. Heero opens the hatch to Wing, and falls helplessly out of the Gundam. Around him is a yellow glow, and he suddenly has hallucinations of Relena, before he passes out. As Quatre sits down beside him, he puts his hand on Heero's back, and the yellow glow leaves Heero to gather around Quatre's hand instead. As Quatre puts the glowing hand to his heart, he closes his eyes and comments that she must be the one on earth... He tells Heero that they should go to earth, because they were nice to them before. As they leave, the Mercurius blows up. Quatre and Heero leave for earth in a shuttle.
