After rewatching R2, I now firmly believe that Kanon was tugging Schneizel’s strings and was basically the mastermind behind almost everything Schneizel did without the prince being aware of it. I believe that the idea to overthrow the emperor was planted in Schneizel’s mind by none other than Kanon; if it worked, Schneizel would hold the throne, but Kanon could run the show from behind the scenes. The scheme first came to him as a revenge plan when Schneizel whipped him (sound episode R2 12.31)”
