"The oldest of the turned...the shamblers. They were nowhere near deserving, they were doctors, police, firemen, nurses, rescue workers, and volunteers among others unfortunate enough to be infected early on. They thought it was a flu and tried to help those in need, and they were ruined for it. From there the better the zombie, the more time survived. The leapers were survivors of the shamblers for a while, then they got bitten in the roaming horde and turned. Specials are the longest to turn, why they came around so late is because of this. They survived the longest before they were bitten, and we are the closest to humans in mental ability. Strange how the least deserving are the most powerful. The clothes on each zombie's back is a testament to who they once were, and who they are forced to be now."
Jack said as a shambler in blue scrubs went by walking with the same speed and ability of a human. Jack noted with satisfaction that the redirection from the auditory to motor cortex was having a good effect, he knew they would never run but they could at least walk like a human, and that was definitely an improvement.
"There goes my point now." Jack said as he pointed to it. "From the scrubs it was either a doctor, surgeon, or nurse. Either way, they didn't deserve what happened to them."
