I just thought of a sad but kinda heartfelt way of Iodore redeeming and sacrificing himself in the future. So basically when Garas gets caught woh the experiments, becomes the big guy and now everyone has to fight her, Iodore starts thinking of past (his relationship with guestella being ruined and his diciples death) and is basically having an inner conflict with himself. After a while of contemplating he then can't take it anymore and decides to attack Garas abd fight along side the gang. This either leads to him making the ultimate sacrifice (fits him in a way of being bug bad but still good in a way and redeems themself by sacrificing character) or he attacks her, survives and joins the gang as a good guy. Although I think the former seems more fitting froma writing/story abd character perspective.
But will only happen if the creator actually doesn't want Iodore to be trash jerk who's only role is to get in the way of the side so called "couple" instead of coincidering what rought might be best FOR A CHARACTER LIKE IODORE AND NOT WHAT ROUGHT FOR HIM WOULD BE MORE "FITTING" FOR OTHER CHARACTERS (*cough* *cough* guestella *cough* *cough*) AND THAT PART OF THE FANDOM (aka the guestella x Kayden shippers).
Well that's all.
