Libra's attack on Barge has begun. Zechs, in his Epyon, also heads in to fight though his White Fang subordinates beg him not to.
The next scene shows Quatre, Duo, Noin, and Trowa readying to fight against both sides of the conflict.
We jump to Heero. He is fighting against some mobile suits on Earth and comes upon Sally Po. Sally has Trowa's Gundam and asks Heero to take it to space with him.
Inside the Romefeller Foundation, the executives are discussing what to do. They are distraught that the only surviving Peacecrafts are at war against each other. Suddenly, Treize walks into the room with some soldiers. He states his intention to lead things. Later on in the day, Treize confronts Relena and tells her that she is released from duty. Treize will become the new representative for the Foundation.
In space, the battles rage on. Things are going badly for the OZ forces now that the Epyon has joined the mix. The Barge fires its beam cannon and blows up a White Fang ship, also partially damaging a nearby colony. Quatre, Duo, Noin, and Trowa arrive. Noin tries to understand what Zechs is doing but she doesn't get any answers. Zechs breaks away from the group after some fighting and attacks the Barge before it can fire a second shot with its beam cannon. The Barge explodes and Zechs disappears in the explosion.
