Nothing is known about Jeanette's life before or as the outbreak began, though she may have lived in or near Woodbury.
Jeanette is seen fleeing the walker attack in Cell Block D.
Jeanette is shown pleading with Carol Peletier not to place her in Cell Block A, telling her that she doesn't have the flu, but allergies instead. Carol doesn't believe her and asks her to go in the cell block.
Jeanette is first seen in this episode playing checkers with Luke. She is later seen stepping out of her cell to see what Hershel Greene and Sasha Williams are doing to a dead man. After the two leave the room, Jeanette returns into her cell.
Jeanette is shown running out of the prison. She quickly gets onto the prison bus. Hershel's daughter Maggie gets onto the bus later and asks Jeanette where her sister Beth is. Jeanette states that Beth left in search of Rick Grimes's infant daughter Judith. Maggie gets off the bus and runs while Jeanette watches in fear. Later, the prison bus drives off with Jeanette and the others.
When Maggie, Bob Stookey, and Sasha encounter the bus on the road, they find everyone inside had turned, forcing them to put down their former friends. While Jeanette is not seen as a zombie, it has been confirmed that all of the prison bus survivors were killed, including Jeanette. There are several bloody corpses inside the bus as Maggie looks for her husband Glenn Rhee, suggesting that Jeanette may have been devoured.
Jeanette was one of the prison residents who escaped on the bus. When Maggie, Bob, and Sasha find the bus, it is revealed that everyone on board had died, either from being shot in the assault or attacked by those who died from the flu and turned on the bus. While Jeanette was not one of the reanimated residents to stumble off the bus, several bloody corpses were seen on the bus, suggesting she was mostly devoured.
