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).
