ninja's may be good medics and all, and i know its all fantasy, but i have to ask...ho ould one go about reattaching every single vein/nerve/etc... in one's eye back into their head, and still be able to see out of it, let alone be able to activate any kind of advanced bloodline techniques the original holder had...i would think there would be an extra "connection" in a special eye...look at it this way: FireWire does not plug into USB...
