Mary Beth Gaskill survives the events of Red Dead Redemption 2 and can be found as an author in Saint Denis after the game’s epilogue.
In Red Dead Redemption 2, Mary Beth Gaskill is one of the members of the Van der Linde gang, which the main character, Arthur Morgan, is also a part of. Throughout the game, she is portrayed as a kind and gentle young woman who often serves as a comforting presence within the gang. Unlike some of the other gang members, Mary Beth is not involved in the more violent and criminal activities. Instead, she contributes by taking care of the camp and participating in less dangerous tasks.
As the story progresses and the gang begins to fall apart, Mary Beth, like several other members, starts to question the direction in which Dutch van der Linde is taking the group. After the gang’s ultimate dissolution, Mary Beth’s fate is left uncertain until the game’s epilogue.
In the epilogue, which takes place several years after the main events of the game, the player, now controlling John Marston, can encounter Mary Beth at the train station in Saint Denis. During this encounter, it is revealed that she has successfully left her life of crime behind and has become a published author. This meeting is brief, but it provides closure to her character’s arc, showing that she managed to find a peaceful and lawful life after the turbulent times with the Van der Linde gang.
