@Phaaze yeah, I curious about that too. We only seen the infected girl for a short time, and she showed no changes other than the visible veins and maybe going feral ??
@Velsy
Well, we only have that one hotel scene to go on where the MC got infected, but he GTFO quick, after which we see another scene shortly after of that woman infecting another, and it ending there.
Time will tell, I guess.
