EXACTLY. I'm afraid to stick with anyone close to me, because if they get bitten, my morale would drop like a freakin' rock. The only person I'd keep with me is Fiona Greer from P.E.I., the best friend ever born. Ever. I'd gladly get bitten for her.
Anyway, yes, Sun, you're right. Seeing as how 75% of the human race is (un)dead and out to rip us apart, I don't think we'll run into too many people, let alone ones that we can become close to and know they'd have your back if you brought knives to a gunfight, figuratively speaking.
I would think there would be alot of one night stands during zpoc. We as humans all get that ''feeling'' and who knows, you
may come across a girl/boy who you find physically attractive and they feel the same way about you. Or maybe your both desperate and need someone to just get it on with lol
