Maggie Greene lived with her father Hershel and her sister Beth in a secluded farmhouse. When Rick shows up on their porch one day with a gravely-injured Carl, Maggie is tasked with finding Lori to relate what's happened.
While Carl recovers at the farmhouse, Maggie pursues a relationship with Glenn and soon develops deep feelings for him.
After spending the winter on the run, the group spots an abandoned prison and Maggie proves herself a capable soldier in helping to clear the yard of walkers. Maggie is also present when Lori goes into labor during a walker attack on the prison. Once Lori realizes she's about to hemorrhage to death, she orders Maggie to cut her open. Maggie does so, saving the baby but losing Lori in the process.
During a supply run, Maggie and Glenn are kidnapped by Merle and taken to Woodbury. The Governor psychologically tortures Maggie, forcing her to take off her shirt and threatening Glenn's life if she won't cooperate. When he puts a gun to Glenn's head, she finally gives up the location of their group.
Maggie and Glenn are eventually rescued, but back at the prison, Maggie withdraws as she tries to cope with the Governor's assault.
Making matters worse, Glenn pushes her to discuss the incident against her will, causing a rift between the two. Glenn eventually apologizes for his behavior, and they make up. When he proposes marriage to her in the prison yard, she accepts with tears of joy.
Maggie and Glenn's marriage is soon put to the test, first when Glenn contracts a near-fatal illness — which Maggie finds herself helpless to treat — and then immediately after the Governor's attack on the prison, when the survivors scatter and she finds herself separated from her husband. On the road with Bob and Sasha, Maggie doggedly searches for Glenn, refusing to accept the fact that he could be dead.
As they follow the railroad tracks, Maggie begins making signs for Glenn scrawled in walker blood, telling him to meet her at Terminus. Eventually, Maggie meets Glenn's former traveling companions, Abraham, Rosita and Eugene on the tracks. The combined group rescues Glenn and Tara from a tunnel filled with walkers, and the couple is tearfully reunited.
Cuddling with Glenn later that evening, Maggie burns a picture of herself that Glenn had kept through his travels. "You don't need a picture of me any more," she promises. "You never will again."
