Olivia (portrayed by Ann Mahoney) is a supporting character in The Walking Dead. First appearing in Season 5, she was a resident of the Alexandria Safe-Zone and had lived out the apocalypse in relative safety and comfort. Before the apocalypse, she had worked in a coffee shop, but since coming to Alexandria she had been made responsible for managing the town's inventory such as food, weapons, etc.
Having remained sheltered behind Alexandria's walls during the apocalypse, Olivia knew very little about the conditions of the outside world before the arrival of Rick Grimes and his group. Being a timid and physically unfit woman, it is unlikely she would have lasted long on the outside. After Rick's arrival, Olivia was often entrusted with looking after Rick's infant daughter Judith and she and Rick shared a mutual trust.
In Season 7, Alexandria fell into the service of a ruthless group known as the Saviours. Olivia would have the displeasure of meeting the Saviours' leader Negan twice, showing him both great disdain and fear. Negan also made numerous comments regarding Olivia's weight, though by way of apology also offered to have sex with her, to which Olivia responded by slapping him.
Death[]
In the Season 7 episode "Hearts Still Beating", Negan and the Saviours have once again visited Alexandria and Spencer Monroe meets with Negan. While playing a game of pool with Negan in the street, Spencer suggests that Negan kill Rick so that Spencer can assume leadership of Alexandria. Negan is offended by Spencer's cowardice and kills him in front of the other residents. Rosita, who had previously demanded Eugene to make a bullet for her, enacts a plan to kill Negan and shoots at him. However, she ends up hitting Lucille, Negan's baseball bat, and Negan becomes furious. Negan's henchwoman Arat pins Rosita to the ground and Negan demands to know where the bullet came from since the Saviours had previously taken all of Alexandria's guns. Rosita lies and says she made the bullet, but Negan doesn't believe her and orders Arat to kill someone at random. Arat raises her gun and turns to Olivia, shooting her in the face and killing her instantly.
