I've found out the Backstory for this,
This is an alternate reality inwhich normal people are black haired, denim wearing, dwarves.
There was a circus a few kilometres infront of the helicopter, and at these circuses they don't have dwarves at their freak shows, they have tall people. These tall people are also black haired Jehovah's wittnesses. Your character has just got a job at a scrapyard/weapons mueseum, he's a good person and he wants to keep this job, even though it's been deserted by the owner due too the zombies, and he is leaving money to pay for the cars and parts.
