Nothing is known about Willy's life prior to the outbreak, other than that he was likely a resident of the Broke Jaw Ranch community and had military experience.
This list shows the victims that Willy has killed:
- Steven (Alive)
- At least 4 unnamed captives (Caused or Direct)
- Possibly numerous counts of zombies and unnamed people
As Luciana and Nick try and escape the military camp through the sewers, Nick opens up a hatch which allows a horde of walkers to flood through. As they both run back towards the camp, Luciana's painful cries and blood leads the walkers back towards the militia.
Whilst patrolling the area, Willy hears a noise in the wall and tries to get a better understanding of what it is. When he opens the grate, several rats pour out of the vent, distracting him until a walker pulls him towards the vent. His face is bitten and he is soon pulled into the small opening, where his body is contorted upon entry and he is devoured by the horde.
