the interesting part is that since Nina would want to avenge Euphemia's death is she going to pilot that 3rd gen knightmare frame vs Zero's superframe - would she get killed as well ?

Clamp/Sunrise has obviously painted Zero/lelouch on the verge of no return [tainted in too much bloodshed] and in no way he can de-activate his Geass; the only way he can go back to school is either to wear an eye-patch or somehow find the connection as to what this VV character has to do with the sudden change of event.

Since Euphemia is dead, there is no way life at school would be the same even after Suzaku's vow to Euphemia to go back to school for her sake; it is ironic that despite Suzaku's insistence to change Kallen's stance to give up her role in the Order of the Black Knights; with Euphemia being broadcasted as the baddie that order for the massacre of the Elevens/Japanese; what will Suzaku do if Tokyo/United States of Japan is formed ? He himself is a Knight of Britannia and an Honourary Britannia; will he give up his role or continue to fight as an Honourary Knight ?

Presumable if Cornelia / Schneizel is not dead by then, how would they reclaimed Area 11 if it has fallen to US of Japan ?
