Jack’s fate after killing Agent Ross is unknown, and there are many theories, which is why I want to know what you think happened.
I, personally, think that Jack Marston fled the law (possibly into Mexico) after killing Ross, and he would be known as one of the last gunslingers of the west, especially since the era actually known as the old west ended twenty years prior. Knowing Jack didn’t follow his father’s (or Arthur’s) advice to live a normal life, which seems like a curse, he probably won’t get a good ending. I speculate that Jack is caught by the United States Government and hung by the end of the decade. Optimistically, Jack could lay low and maybe flee the continent, but I think thats unlikely. Others think he may have joined WWI, which idrk about. What do y’all think?
