Suzaku is fighting Kallen in the new Guren. The new machine is so powerful that it rips Suzaku a new one. Nina is constantly screaming at Suzaku to use Freya.
Suzaku silently refuses to use it and resigns himself to death.
Only too late does he remember he has been geassed to live.
He shoots the nuke at Kallen, who dodges, and it goes flying into the capital building. Nunnay's escape ship is caught in the blast. Asahina is also killed, along with Guiliford who dies pushing Lelouch to safety, thinking Lelouch is Cornelia.
Shit got real.
