As unfocused as that swipe is, it's really pathetically easy to dodge. Truth be told, he's been wanting to punch Eiji for a good while now over all of this. He's just been afraid to with the purple Medals being what they are, but well... Maybe it's an effect of being just that much more volatile thanks to having memories messing with him all the time, but right now he's thoroughly decided not to care about that risk. And to punch Eiji in the gut because it's satisfying.

"What the hell is wrong with you, Eiji? Are you trying to get yourself turned into a Greeed? I didn't think even you would be that stupid."
