Stuff I’ve been thinking about but don’t know if I’ll ever have the chance to properly establish in canon

Basically the ghost virus changes a person by activating pieces of junk DNA which will then manifest in the body over time as the cells get replaced naturally. Things like stronger bones and muscles, but I’ve been thinking of some subtly weird and creepy details as well. Teeth might grow back when knocked out? And they’d grow a bit sharper than necessary, like an animal’s teeth??

I dunno, if there’s a genetics expert out there feel free to call me out on my bullshit! But I kinda like the idea that the human genome would carry leftovers from previous stages of evolution which the virus then uses to “improve” it’s host
