"Realistic" choices: (seems odd to say given a zombie senario, but whatever)
Myself

3 random 20-something women.
We're not going to survive, no matter who I pick, so I might as well try to convince the girls to enjoy some safe-house entertainment... before the zombies beat down the doors and tear us to bits.
Unrealistic choices:
The hero from fable 2: He never dies, just gets scarred and then stands up again.
The hero's dog: Because damnit, he loves that mutt, and he'd refuse to help if he couldn't relieve stress by playing squeeky ball with it.
A baby/toddler small enough for me to reasonably throw: Emergency zombie bait.
You were expecting a woman of some sort, and I did honestly consider adding one to the team, but then I knew that the fable 2 hero would just keep spamming emotes at her until she hooked up with him, and... well that'd be pretty depressing to be the guy stuck taking care of the zombie bait while they shagged.
