Series 1 EditWhen Thomas Shelby finds out that Lizzie is to be married to his brother John Shelby, he confronts her, offering her eight pounds to see if she is still a working prostitute. When Lizzie takes the money, thereby failing Thomas's test, he informs John, who then calls off the marriage. Despite the unfortunate circumstances, Lizzie and John end up remaining friends.
Series 2 Edit
Two years later (1922) Edit
In his office, Thomas asks Lizzie to type on a typewriter, with her eyes closed, "If winter comes, then can spring be far behind?" He offers her a job as a secretary for his expanding Shelby family business, offering to pay her eight pounds and four shillings a month, telling her she can stop her prostitution work permanently. Lizzie accepts the job.
Lizzie was present at the new grand opening of The Garrison Pub.
At the Epsom Races on Derby Day, Lizzie is escorted by Jeremiah Jesus to Thomas Shelby, who had told her he had a job for her to do. Lizzie finds out that the job involves playing the role of a prostitute, and luring a soldier named Field Marshal Henry Russell to a quiet place when the races begin. Though she initially resists, she does the job for Thomas. Before Thomas leaves, he promises to save Lizzie before she is forced to sleep with Russell.
Thomas is late to find Henry Russell (who attempts to rape Lizzie), but eventually Thomas succeeds in killing the man but not before Russell rapes Lizzie. Lizzie points Thomas's own gun at him in anger, and shoves him backward before leaving the races.
Series 3 Edit
Two years later (1924) Edit
Lizzie tells his brother Thomas that John is "a good man" and that she loves him. However, this still isn't enough to stop Thomas from telling John about Lizzie's continued prostitution work.
Despite the fact that she didn't end up marrying John, Lizzie continues to be good friends with him. When she is emotional after her bad experience at the Epsom Derby, John comforts her. Lizzie doesn't correct his mistake, instead reminding him of how much better of a man he is than Thomas, and that she thinks he should leave the Peaky Blinders gang before it potentially ruins him too. These honest words from Lizzie leave John speechless for a moment.
At first Lizzie resents Thomas for ruining her potential marriage with John and for manipulating her into telling him about her prostitution work. In the second series, she continues to work for him. In season 2, Thomas asks Lizzie to seduce a military officer as a distraction. Though Lizzie is clearly uncomfortable with the notion of reverting to her old ways, she does so anyways, but not before Thomas promises her he will return before it goes to far. The officer is seen forcing himself upon Lizzie to her dismay, and Thomas quickly stops and kills the man in the nick of time. They maintain a strained relationship but manage to coexist peacefully.
Lizzie Stark is a good friend of Jeremiah Jesus the street preacher, who escorts her to the Epsom Derby to do a job for Thomas. She was also seen sitting with him at the bar of The Garrison Pub during its reopening as Arthur's new pub.
Lizzie is also a friend of fellow Peaky Blinder Arthur Shelby, who joins the company of John and Lizzie while they are speaking briefly at Epsom.
