 * I want absolute power, so it would be ridiculous to even think of challenging me or even considering the thought of fighting me at all.

 * It's just that my power's too strong. My hormones are out of balance or somethin' because there's barely any outside influence, so now I've got this androgynous body.

 * Yeah, I killed ten thousand of those Sisters. But that's no reason to let the other ten thousand die. I know that sounds hypocritical. I know the words coming out of my mouth right now! But you're wrong! We may be the epitome of human trash, but no matter what your reason is, there's no f**king way it's okay to kill that kid!!

 * So here I am. And to think I was wondering what kind of delightful idiot was responsible for causing me all this pain... So who the f**k is this underling?! Are you making fun of me or somethin'?! I didn't need to come all the way out here for this pile of dog shit! At least tell me beforehand it would be some dumb underling! Do you have any idea how much trouble you caused me?!
