That chapter wasnt so bad, sure, Arnest still had to be the dumb bit** she used to be for some time now, but still, compared to the trash chapters that came last it got better.
Despite really liking the new character part of me actually wanted her to die and someone to point out that it was basically their fault for telling her to disconnect from mother in order to beat up Blade. That would have felt really satisfying.
Iona is actually quite a popular character. Enough to even earn her a Spin Off focusing on her and her wacky daily life with other characters.

Oh I don't know what happened there but I fixed it ( It's the bubble @ bottom right)... I did most of this ch with a massive headache since I have a cold so I must have been not reading at all. Good thing I decided to randomly read comments, thanks
