"I could look into your mind, but I have no desire to do so. Doing such a thing seems cowardly, don't you think? And yes I could use this multiple times, but because this eye is not my own my body treats it like a virus when it activates. My body attacks my eye and either makes me go temporarily blind or makes my eye bleed. My brain later suffers from the anti-bodies making it swell up against my skull and later imploding. Of course this is the worst case scenario. The worst I've gotten so far is a minor headache. Sorry if the news troubles you."
