Walker lived a pretty average life for a Australian kid, smoked pot, and enjoyed life. Although if you asked people who knew him well but not well enough they described his as quick to anger and a bit narcissistic. One thing that particularly set him off is if someone made fun of his style or his rare but occasional stutter. He eventually ended up in Chernarus because of a self funded trip around eastern Asia and Europe. This is when he found himself stuck in Miroslav. In a country he was unfamiliar with and surrounded by scared tourist and civilians alike. During the Apocalypse a CDF member thinking it would be funny made fun of his stutter and Walker threw a punch, then proceed to get his shit kicked in. After this he elected to leave and snuck out in the middle of the night.
