Even if we became a multi-celled colony after turning, our cells would still need oxygen and food from a functioning circulatory system. Jellyfish are able to feed by osmosis because their skin is extremely thin - we cannot. We depend on circulating blood. Also, a human body is full of bacteria that is kept in check by our immune system. If white blood cells cannot circulate or reproduce, every cell In the body would die and rot from bacteria in a matter of hours. And the aquarium scene made no sense to me. Are those suppose to be his trophies? Because I believe two of the heads there were the zombie Sherpas that Michonne killed.
