Andrea was there when Lelouch and Suzaku took command of Euro Britannia and he would no doubt recognize Lelouch once he became Emperor. What is his opinion of them prior to them prior to and post Zero Requiem? Once Suzaku as Zero shook hands with him to integrate Euro Britannia into UFN, how much does he reminisce his time back in E.U. as the former White Death of Britannia? Andrea does not know that he is shaking hands with the man who is hated in Euro Britannia and E.U. but at the same time Suzaku is making amends to stabilize the very world Lelouch created.
