What's the song that plays in Code Geass R2 episode 25 after Todou collapses? At about 5:55 through Episode 25 of R2, Tohdoh collapses and a song begins to play. It continues to play over several of the characters' declaration of their reasons for fighting. What's the song? I've searched through the OST as well as unreleased tracks but haven't been able to find it.

The episode can be watched here:
