In 1906, John Marston was badly wounded in a botched bank robbery. John took this as an opportunity to abandon his life of crime after it abandoned him, as John often puts it. He left with Abigail and Jack, moving them to a ranch on Beecher's Hope to try and start over as ranchers and give Jack a better life. He and his Mother were held hostage by Edgar Ross, who used them as ransom to get John to hunt down and kill his old gang. After John completed his task, the two were released. After which, John began spending more time with Jack, teaching him how to skin deer and elk, herd cattle, and become overall a better cowhand. Jack ran off to hunt a Grizzly, trying to prove he was a man to his father, John managed to save Jack, but not before Jack recieved a scar almost identical to his father.
When Edgar Ross brought the U.S. military to kill John once and for all, Jack helped John to fight them after Uncle was mortally wounded. Jack and his mother escaped, but John was killed. Three years later, Jack hunted down and killed his father's murderer, Edgar Ross.
