Nothing is known about Bob's life before the apocalypse except that he had a wife.
At night, Bob is in Jake's house with Pat Daley and several other residents complaining about the rationing of the water. He states that he "pisses two gallons" in the morning and that amount of water won't be enough for him. When Alicia interrupts the angry residents, she is able to calm them down by reminding them that Jake is trying to keep the peace despite losing his father and brother. Bob calms down and shakes Jake's hand in gratitude for all he has done. The next day, Bob is at the well collecting water when Alicia catches Kerry taking more water than she is allowed, sparking a small scuffle. He scolds Alicia for not informing everyone sooner about the severity of the water situation.
Bob is among the ranchers to evacuate to the underground pantry. As Alicia hands out drinks to the surviving ranchers and Natives, an upset Bob asks Alicia where his wife is, indicating she may have been among those killed when the horde broke through the RV wall. He stands between the shelves as he listens to Alicia addresses the crowd regarding those bitten. Later, Bob is seen dead as Alicia fights off the reanimated ranchers and Natives in the pantry.
Bob is among those to suffocate due to the lack of air and was later devoured by zombies.
This list shows the victims Bob has killed:
- Possibly numerous counts of zombies
- This character is credited as Rancher Bob in the credits for "The Diviner" and "This Land Is Your Land".
