Glenn meets Rick during one of his frequent trips into Atlanta to scavenge supplies. After witnessing Rick's assault by walkers, he guides Rick to safety via a handheld radio. "Call it foolish naïve hope," Glenn later explains, "that if I'm ever that far up shit creek, somebody might do the same for me."

Glenn used to deliver pizzas for a living, and his knowledge of shortcuts, his agility and his fearlessness prove extremely useful to the group's scavenging needs. As Rick says when introducing him to Hershel’s daughter Maggie, Glenn is “our go-to-town expert.”

Maggie begins to accompany Glenn on his supply runs, and a romantic relationship ensues. But the two often find themselves at odds, first when Glenn spills her secret that walkers are being held in Hershel’s barn, and later when she chafes at his willingness to risk his life running errands for the group. “You’re walker bait,” she declares.

Nevertheless, the relationship flourishes and Glenn earns the respect of Maggie’s father. “No man is good enough for your little girl,” Hershel says, “until one is.” And although his affections for Maggie lead Glenn to reconsider his daredevil lifestyle, he eventually comes to embrace his feelings, telling Maggie, “I love you. I should have said it a long time ago and it’s been true for a long time.”

Glenn is an integral part of the camp, bridging the gap between Rick’s group and Hershel’s and showing depth and humanity while helping others through their various crises.
