Betrayed by Home, Far Away
Back in space, a female special envoy of OZ urges the warring parties to stop the fighting. Test of the mobile suits in space has begun, but the lady doesn't think she needs them for protection when she travels to a peace meeting as the colonies sees MSs as their enemies.
At the conference, she speaks about peace, and that the opression of the Federation now can end because the OZ is here to liberate the colonies. Before she leaves, it is revealed that the mild mannered female with the soft voice and appearance actually is Lady Une.
On earth, Duo and Quatre get news about the OZs latest move to market themselves as the peacekeeping liberators of the colonies, and decide that something must be done. They see through OZs lie easily, and think that they're only switching from one opressor to another. The people of the colonies are far too careless, in the Gundam pilots' eyes. Quatre think that they should return to space with their Gundams, because they were made for the colonies, after all. Quatre means that they should go back to space and deliberately show that they're doing so, because the OZ can't use the colonies against them anymore if they're going to act as peacekeepers.
Some colonists embrace OZ support, while others are more suspicious of OZ.
The work to clean up space from mines between the colonies resume, and Lady Une gets a report that they've found a possible Gundam factory on a colony. As she goes to interrogate the captured Gundam scientist, she's back to her old self again. She finds out that the scientist only made one Gundam, and that there are four other scientists. The scientist laughs as Lady Une suddenly gets a report about Gundams appearing at the Space Port on Singapore, attacking it. He suspected they would return to space, and he was right.
At the Singapore space port, a battle between Gundam 02, 04, and the OZ forces begin.
The colony leaders are horrified that the Gundam has appeared again, and thinks it'll ruin their newfound peace with the OZ. The colony leaders decide that they must act against the Gundams or OZ will lose their faith in them. Only one colony leader protests, and understands the Gundam pilots' true purpose.
Meanwhile at the battle, the two pilots gets the news that the colonies have turned against them, and allied themselves with OZ against Gundam, who they hope will soon be destroyed. The battle intensifies, and things are starting to look really bad for Duo and Quatre, when Wufei suddenly appears and saves the day. On the nes broadcast, they can see that Trowa and Heero have both joined the battle elsewhere, and that the're not alone anymore. Even if the colonies doesn't underestand, the other Gundam pilots do.
Elsewhere, Lady Une has captured four of the Gundam scientists, but the fifth one is still resisting capture at a colony. She orders the colony to be shot down in order to kill the scientist, and when someone protests, she asks when fighting for OZ ever became decent. She thinks that this isn't diplomacy, it's war, and that the colony will have plenty material to rebuild with once they've destroyed this. When the Gundam scientist hears this, he surrenders, happy to see that the OZ still retorts to dirty methods.
In Singapore, Quatre realises that there's no way they can all go to space, someone must stay and distract the OZ forces, and Quatre volunteers himself, telling the others to escape. Quatre thinks there's only one way to finish this, and presses the self-destruct button to blow himself up, but Sandrock opens the hatch and lets him escape first. As the three shuttles launch into space, Sandrock explodes, taking the base with it.
The Gundam scientists are re-united, and Dr. J scolds them for giving up too easily. Dr. J comments that he didn't think they all would succeed in making Gundams, but it's nice to meet his old partners again after 15 years.
As Lady Une in the space control room gets reports of the Gundams launching into space, she orders them to be shot down, when suddenly all alarms goes off to make it impossible. It appears that all communication frequencies have been jammed... Dr. J comments to himself that it was a bad idea for OZ to let them stay alive.
