Bro we was thinking the same like i was scrolling tiktok and found this what i could tell is that he lile half himan half zombie or like zombie body but human brain type of thing. And i read the first chapt and it said he had cancer. So the first thing that came to mind is a virus fighting virus since zombie virus is virus. So i was like cancer v.s. zv (zombie virus). With that happening the virus can't get the brain. So it took the body and it went poof zombie body.
