For a supposedly omnipotent being you are rather thick. Is it your ego that blinds and deafens you to all else? Or your "power". I wouldn't tell them of the glaringly obvious, simply inform them that you are willingness to make a depressed young girl even more miserable. A girl that was Mitchell's child. And remind them of the sacrifice Mitchell made for all of us. In a fight where you were unsurprisingly absent, archangel.
I am not afraid of you. Your father is not my god. Mine stood beside me, fought beside me and bled beside me. And I have slain more than one of your kind in my time, and have learned of quicker ways since. Though you are such an undeserving coward I wouldn't fight you, if it came down to it, I would just push you out an airlock.
