Nothing is known about Tommy's life prior to or as the outbreak began except that he may have lived in the area surrounding Alexandria.
Tommy is seen at Deanna Monroe's party. He spends his time socializing with the new arrivals and other residents. He, like the rest of the partygoers, are stunned by newcomer Sasha Williams' outburst.
Tommy is working at the Woodlands Mall construction site gathering materials with Abraham, Francine, Bruce, Tobin, Jake, and other Alexandrians. When the site is attacked by zombies, Tommy is among the survivors to respond to the attack, helping save Francine who was injured from a fall.
Tommy is among the townspeople present at the community forum to discuss Rick's fate after the brawl in the streets the day before. He also witnesses the murder of Deanna's husband, Reg, and the subsequent execution of Pete Anderson.
Tommy is present at the meeting in Deanna's house regarding Rick's plan on what to do with the walkers at the quarry. He is among the townspeople to help build a wall outside the community to prepare for the mission to lead the herd away. He is also at the quarry to help execute the mission with the other survivors. When the herd breaks free, he flees with Francine and Bruce's group out of the quarry to their assigned post.
With the herd on the move earlier than expected, Tommy heads out to his assigned location. While in the woods, he heard someone calling out for help, prompting him to turn back to find the source of the cry. However, he tripped in the woods and severely injured his leg. He managed to make his way back to the road but was overcome by zombies. A short time later, Rick finds Tommy's body and prevents him from reanimating.
