Crossfire at Barge.Treize dismisses Relena from her position because he reasons, now that she has laid the foundation for peace, he will provide the military might required to bring it to fruition. As she and Dorothy head for space separately, so do Heero and Sally, taking along the Wing Gundam Zero and Trowa's Gundam Heavyarms (which Sally has recovered). When Duo, Trowa, Quatre, and Noin intervene in the White Fang's attack on Barge in hopes of finding out why Zechs has declared war against Earth, he makes his intentions clear by singlehandedly destroying Barge with the Gundam Epyon's beam sword.
