Lelouch got up from his thrown and walked towards the prisoners he first walked up to Kallen and said quietly "Q1 I always loved you but I must do this".
He then walked up Tamaki and said loud enough for everyone to here "back when I was still zero I always hated you because you were so stupid though your stupidity did save me at one or two times".
He walked to Tuodo and said "you were said to be a miracle worker although you kind of never made me any miracles and made me do all the work ohh and by the way I technically did fulfill my promise Japan was liberated for a short period I admit but a period all the same".
He walked up to Ohgi and said "although you were technically smarter than Tamaki in common sense you were severely lacking you could have just hatched a plot to unmask me in front of the rest of the black knights leaders and this whole scenario could have been avoided".
An with that just as he was about to give the order to shoot zero came running up the street.
You know the rest and all the people who think he's dead "is not"
