I tried to kill him too.

[And, to his shame, his biggest frustration right now was that he didn't even 'finish' that battle. He ran. He didn't lose, or win, he just cut it off to deal with his own pressing visual issues.]

I attacked him, and the more power I tried to use, the cloudier my vision got, until...

[He lowers his head then, making the long bang that is Zexion's signature look hang forward too.]

It happened again - using that power I stole causing this to happen. I knew the risk, I just wanted to kill him so badly... After I realized - about how I looked - then I came here.
