He was quite an odd zombie, you could barely tell he wasn't human. He was a bit off-putting like any other zombie, but he seemed almost friendly. He would do whatever he could to help you, no matter if you wanted his help or not. He had no desire to eat you or any survivor, he found it repulsive. It was like he had a sense for other zombies, and he easily led them away from you. He also was incredibly fast and strong, far better than any regular zombie. How odd.
