AndreaPlayed by Laurie Holden
Andrea is headstrong, opinionated and extremely protective of Amy. But when Amy is killed in a walker attack, Andrea becomes distraught, lamenting to Dale that "there's nothing left," and opting to stay inside the CDC as it self-destructs rather than live on. Dale, however, convinces Andrea to leave the building by vowing to stay as well.
Andrea's new lease on life comes with a desire to protect herself and the group, which she accomplishes by forging a friendship with Shane. He, in turn, teaches her everything from gun maintenance to sharpshooting, at which she excels.
Never one to shy away from a fight, Andrea is instrumental in defending the group against a herd of attacking walkers one night, but in the ensuing chaos, she gets left behind.
Alone in the woods and out of ammunition, Andrea is about to be bitten by a walker when its head is sliced off.
As the walker's body slumps over, Andrea sees standing before her a hooded stranger wielding a katana sword. The figure is Michonne, and the two become close traveling companions.
Andrea and Michonne are abducted by Merle Dixon and taken to Woodbury, where they meet the Governor. Andrea is immediately taken with Woodbury and decides to stay even after Michonne, who is suspicious of the Governor, leaves. She becomes the Governor's lover and assists in his efforts to keep the town safe. When she learns that he corrals walkers to fight in gladiator battles, she bristles and calls it "barbaric" but admits it also excites her.
Gradually, Andrea learns about the Governor's cruel nature. When she discovers his plans to attack the prison, she tries to broker a truce. The Governor pretends to strike a deal with Rick but secretly plans to kill everyone.
When Andrea finds out his intentions, she escapes Woodbury to warn Rick. The Governor chases her down and ties her up in his torture chamber. He kills Milton and locks them in together.
Before he dies, Milton asks why Andrea stayed with the Governor even after learning Rick and the others were still alive. "I wanted to save everyone," Andrea says.
Milton reanimates and attacks Andrea, ravaging her neck. After defeating the Governor at the prison, Rick brings a team to Woodbury, where they find Andrea on the throes of death.
Using Rick's gun, Andrea shoots herself with a tearful Michonne at her side.
