GGA Soonk - He has guns and survival gear, and he'd be willing to make those very difficult decisions...IE killing humans.
FrothyOmen - Cause he and soonk work well together, and he's always willing to play devil's advocate.
CrimsonShadow - another good friend who is smart, and could play the group conscience. He's also got connections and knows about computers enough to possibly help us get some sort of technology building for our commune.
Pig of the Hut or Tom brady - both are fun and friendly guys, who seems like they would be willing to be the democratic voice in case we came upon some other groups... and they could convince the lone women to join our group.
The last spot is the hardest.... I'd have to say TomLulsBrady, and here is why....
When the chips are down, and we as a group need to make that step from trying to survive by killing zombies, to surviving by killing humans, I want a person that does nothing but troll so that my rage could help me get through the horrible horrible thing I would have to do.
Also, if I took out TomLuls then Tom Brady would be really happy and want to hang out with our group of nobodies.(and soonk)
