Lelouch has to arrange an alliance with a Kyoto, group that funds rebels.
Shirley has to identify her father's body. He was killed by Zero's actions in the prior fight.
Zero throws good effort after bad and uses the JLF as bait for Cornelia. The win will justify the deaths.
Shirley follows Lelouch to see what he's up to and comes to the battle.
When Lancelot interferes to save Cornelia, Zero ejects and lands next to Shirley. She sees his face.
