The Sorrowful Battle
Noin arrives at the South Pole base with Heero and Trowa, and they meet with Zechs. Zechs asks Heero if Heero Yuy is his real name, as he recognises it from the famous colony leader. Heero retorts with asking Zechs is that's his real name. Zechs takes them to the mobile suit hangar, where Gundam 01 is being finished, much to Heero's surprise. Noin asks Heero is he isn't going to thank Zechs, but Heero only tells her that he'll show his appreciation by killing Zechs. Zechs realise he's just a nuisance to the Gundam pilots.
Relena has arrived to lake Victoria base, where she demands to see Zechs or Noin. Unfortunately, the mechanic she talks to won't tell her where they are. Pargan gets a phonecall, obviously with the information Relena wants, and they leave. Afterward, the mechanic calls Noin and tells her about the meeting. Noin assumes that if the Peacecraft family can find out about the Gundam, so can the Romefeller foundation. Noin doesn't understand why the Foundation hates Zechs so much that they must have him killed, but Zechs offers his explanation. Zechs means that the difference between him and the Gundam pilots is that they have devoted their entire life to the battle of saving the colonies, while he is just a soft soldier. Noin protests, Zechs does have something to fight for. Zechs then orders Noin to take care of any distrubances to the battle, as it will probably be long, especially interfering members of the Peacecraft family. Noin comments to herself that Zechs weill be a real soldier when he fights for Relena.
In the Gundam hangar, repairs on Gundam 01 and 03 are underway, and Heero says he'll use Heavyarms for this battle, as his newly returned Gundam is too well fixed, he would feel wrong using this superior suit in a battle. Since 01 isn't going to be used, Zechs' mechanics asks him if they should take back the spare parts from Tallgeese used on the Gundam, but Zechs tells them to leave them in, it'll be a fair handicap for him when he uses Tallgeese. Heero stays up late to fix the Gundam, and when he goes to bed, Trowa makes other alterations on it because Heero is still too injured to fight the battle.
Early in the morning the next day, the re-match between Heero (in Heavyarms) and Zechs (in Tallgeese) begins. After three hours of battle, Trowa comments that the pointless feud is getting rather long. Noin protests, the battle isn't pointless! They argue a bit of the true meaning of the battle before Trowa points out the obvious - both the Gundam pilots and Zechs are fighting OZ, so why fight each other? Trowa leaves to prepare for any interruptions, as he sees the battle pointless.
Relena finally finds the South Pole base, and encounters the investigative group who orders her plane to turn around, the area is a battlefield. Relena refuses. As the OZ commander orders Relena's plane to be shot down, Trowa appears in Gundam 01 and chops the OZ suits up. Relena sees Gundam 01, and thinks it's Heero, but Trowa tells her that he's fighting a bit away. He then asks her why he's here anyway as he points 01's vulcan gun at her plane, but when Relena states she's there to stop the pointless battle, he lets her leave.
Back at the battle, Zechs is about to deal Heero the killing blow as Relena shows up at her plane. She insists on giving Heero Mrs. Noventa's letter, stating it has important information for how he should live his life in it. Zechs thinks Relena has become strong, a true Peacecraft, but he feels he must show her how dirty war is, and continues fighting Heero. Relena finds this cruel, and orders Heero to kill Zechs. Noin lectures Relena on things, and finishes with a plea for Relena to not want her brother dead... She then explains who Zechs really is. Because of what OZ turned into, what defines Zechs as a soldier is having Gundam as an enemy.
The investigative group of OZ eventally found the base, and over 100 mobile suits attacks. Trowa thinks they could easily handle it, it's only 30 suits for each of them, but Zechs orders them to leave and save their colonies instead, he'll take on the OZ himself. As he leaves, he tells Heero that they'll have to finish their duel some other time. The both Gundam pilots leave, and Zechs orders Noin to take Relena into safety.
