|“||There's a good man within you... But he is wrestling with a giant.||„|
|—Mary's last words to Arthur|
During her youth, Mary was in a romantic relationship with Arthur Morgan and the two were deeply in love, but it ultimately fell through due to Arthur's life as an outlaw and affiliation with the Van der Linde gang, leading to prevalent disapproval of her family as a result, particularly her father.
Afterwards, Mary eventually married a man named Barry Linton and took on his surname, but Barry later passed away after contracting pneumonia, leaving her a widow. To make matters worse, her family grew to be dysfunctional as well. Her brother Jamie had joined Chelonia, an infamous fanatical cult. Her father gradually became more withdrawn and verbally abusive to his children, growing increasingly dependent on alcohol, whoring, gambling, and eventually began pawning off much of their family's property.
Events of Red Dead Redemption 2
Horseshoe Overlook Chapter
Mary contacts Arthur for the first time in many years. She pleads for his help convincing Jamie to leave the Chelonians. Arthur is apprehensive due to poor relations with the Gillis family but admits that he was at least on good terms with Jamie. If Arthur accepts, he successfully chases down Jamie and convinces him to leave the Chelonians. He then takes him to Mary at Valentine train station. Mary and Jamie board the train to return home and Mary thanks Arthur for his help. After this, Arthur laments how he feels both elated and foolish for how Mary can manipulate him and resigned to the fact that he wouldn't be able to refuse her. It appears as though Arthur still has feeling for her at this point, as he writes their initials in his journal with a heart between them.
Saint Denis Chapter
Mary later asks Arthur for help with her father, much to Arthur's ire. Mary begs for his help and tries to justify her father's poor treatment of him, but Arthur angrily points out that Mary's "pure life" hasn't fared much better either, referencing Jamie joining the Chelonians, Mr. Gillis' deeply hypocritical and deplorable habits, and the fact that she was now begging him for help. If Arthur accepts, he accompanies Mary to Mr. Gillis, who verbally abuses Mary before storming off. Arthur and Mary follow Mr. Gillis to an alley and discover him pawning a brooch gifted to Mary by her mother. Mary angrily confronts her father, as Arthur goes to take the brooch back from Ashton. After Arthur gets the brooch, he returns to the alley and finds Mary sitting down dejectedly, expressing indifference to wherever her father went.
After the situation with Mr. Gillis, Arthur offers to take Mary to the trolley. On the way, Mary asks Arthur if they could go to the theater together instead as friends. If Arthur accepts, he takes Mary to the theater and the two begin to warm up to each other and reconnect. After the performance, Arthur walks Mary to the trolley. As they reach their destination, Mary laments the deteriorating state of her life and asks if it's too late for her and Arthur. Arthur admits that he does want to run away and be with her, but states he doesn't want Mary to get hurt, he has people in the gang to take care of, and that they need money. Arthur promises that as soon as he can get the money they can run away. The two part ways again for the final time.
Beaver Hollow Chapter
Arthur later receives a letter from Mary, enclosed with the engagement ring he gave her many years ago. In the letter she says her goodbyes to him and that it was time to let each other go. She acknowledges that Arthur is unlikely to ever leave his life behind and apologizes for how their relationship turned out. She hopes that the ring can be passed down to another couple in love in order to help them too.
Mary's final words to Arthur are some of what he reflects upon during his last ride.
Mary is a well-meaning woman who tries to see the best in people and most situations. She loves her family but tries to see past its apparent dysfunction, the brunt of which is attributed to her father.
She loved Arthur and desired to have a life with him, even retaining feelings for him over the years. However, she acknowledges that Arthur's preference for his criminal lifestyle would prevent them from ever having a future together, eventually coming to terms with it and deciding to cut ties with him. Despite that, Mary visited Arthur's grave and wept for him, showing that she still loved him enough to overlook his faults.
Mary has long dark brown hair, tanned skin, brown eyes, and a beauty mark on her right cheek. In her first appearance, her hair is tied back in a low braid and is then tied back in a low bun for the rest of her appearances.
