Diokletian is on my list. My list of characters that are mean. On the one hand he has feelings for Felix because he was in love with Felix's mother (Methony) and on the other hand he's calling Mildmay, who is also Methony's son, a 'trained bear'.
If he really cared about Methony he wouldn't talk about her son like that. True, Felix might be Diokletian's son and Mildmay definitely isn't, but still. Nobody is allowed to insult my Milly-Fox. NOBODY.
At least Felix stood up for Milly. Keep up the good brotherly work, Felix!
