Nothing is known of the mile marker's history before the outbreak.
In a flashback, Purvis is seen leaving a box of supplies on the road, when suddenly, he is ambushed by Martha and her pet walker. A panicking Purvis asks why she is doing this. She insists it's because people need to learn to care for themselves and help makes them weak.
Martha demands to know the identity of Polar Bear, the person who organized the box distribution. When Purvis refuses to answer, she releases her walker pet onto him and watches as he is bitten, before going for the truck's CB.
