Little is known about Billy's life prior to the outbreak. He lived with his mother, Hannah, and had weekend visits to see his dad, Andrew in King County. It is unknown but he may have attended school with Carl Grimes since the school is in the nearby area of King County however, they may or may not have known each other.
After the car accident and noticing his mother was unconscious, he and his sister, Jamie, head to their father's house to be rescued. He and his sister reside there under the care and protection of their father and are then joined by their mother later after she wakes up and arrives at the house. They are reunited with their mom and the family becomes whole again. While Andrew tends to his former wife's wounds, Billy becomes curious and wonders where Max, the family dog, has gone to. He goes to the living room and gets his dog bowl and then heads to the kitchen to ask his father if he has seen Max. Andrew firmly insists that Max is okay and tells Billy to put the dog bowl back since it wasn't his dish. While the parents discuss the growing risks of staying at the house, the family decided that they should try to get to a safe zone in Atlanta. While the parents gather supplies for their trip, Billy continues looks out the dining room window wondering where the dog could be while his sister eats peanut butter. Billy's step mother, Judy is infected and rolled up in a rug begins to move about. Jamie notices this, grabs Billy while covering his mouth to prevent him from screaming and both hide under the dining room table. When the walker doesn't see them, Billy and his sister head to the closet to hide however, the walker notices the closet door closing and bangs on the door to get to him. Billy and his sister both scream for help and their mother comes to the rescue and kills the undead corpse of their step mom Judy. The family decides to escape. They will need a vehicle, his sister, Jamie, mentions that the neighbor, Mike Palmer has a pick-up truck at his house. His father, Andrew, not knowing how to hot wire a car, decides to go and get the keys to the truck at Palmer's house.
Since his father did not return, his mom decided to flee the house and get to the park evacuation site. Billy runs along with his mom and sister down the street until his mom sees an abandon car. She gets in to find the keys still inside but unfortunately is bitten by a walker sitting in the back seat. His mom comforts him and his sister and tells them to run for the evacuation station. Hannah lets herself get torn apart by walkers to allow her children to escape.
It was later revealed in "Chupacabra" that the refugee center Billy and Jamie were being taken to eventually fell. Whether or not Billy survived the destruction, or even made it to the refugee center remains unknown.

- Possibly numerous count of zombies
Although not much seen interacted, it can be assumed that the two had a good relationship to each other. Billy has been shown to care for his mother very much. In final episode of The Walking Dead Webisodes: Torn Apart, Billy is seen crying while running with his sister as their mother is devoured by the walkers.
Jamie is the eldest of the two siblings. Both of them seem to have a good brother-sister relationship. Billy is very much protected by his older sister, as seen when she takes quick action to save Billy and her from getting devoured by their stepmother, Judy.
Throughout the webisodes, Billy shows concern in Max's welfare. After Max was bitten by walkers, Andrew keeps the truth away from Billy, telling him that Max is only sleeping. While Billy believes this for a short time, Jamie angrily tells Billy that Andrew had been lying to him and that Max was dead. Mid-argument over Max's whereabouts, the kids are attacked by Judy, ending the argument and leaving Billy's beliefs on Max's condition unknown.
