Someone should really tell Suzaku that if he's gonna change the world from the inside, well he better get started on it, cuz he's already as "deep inside" the Brittanian chain of command as he's gonna get... He's already close to the emperor, and I don't think he can change him with his so-called "ideals"
Right now he's nothing more than a dog doing the bidding of the biggest cause of strife in the world, and if he intends to help conquer the whole world before carrying out his "change" he's one big fool, utopia is just an ideal
