Battle continues between Orb and the Earth Forces.
Lord Uzumi explains to Cagalli that the world is going to be caught between two groups lead by people who cannot acknowledge that the other side has a right to live. He also reveals that Kira is her twin brother.
And then he makes her get into the shuttle to take her to space.
Athrun and Kira fight the Earth Forces first then they have to fight to get on the shuttle before it leaves the mass driver launching it into space.
Then Lord Uzumi and the other government members activate the self-destruction of Morgenroete and the mass driver to prevent the Earth Forces from using either.
This is an emotional episode. Lord Uzumi is giving Cagalli his last words and Cagalli loses her father.
