We can call it Hulk out. I don't think there's copyright issues here. I'd be immune. The Mark keeps me ticking through everything. Zombie virus included. I kind of want to try if I'd be immune to everything at this point. Overcoming death gets easier over time. Not relationships though.
If you ever get the urge to try...I can lock you in the morgue and let you get your brain munchies out on the corpses.
I overlook it because you're a reasonable person who is aware of the risks and willing to warn people. Rather than just let them come to the conclusion by surprise. You're already one foot in the door, I'm already half-way to the morgue so you don't get too depressed. I might be bringing a blender.
