Hello everyone, this is my first post of this wiki. I myself do not play GTA, but I have played Red Dead Redemption and my brother plays GTA. In GTA, when you walk into Franklin’s house, you can find a book on the bookshelf called Red Dead - J. Marston.
This obviously connects to Jack Marston, and it’s such a cool Easter egg! Not only does this mean that Jack pursues his dream of writing, but he even possibly turns out okay after the events of Red Dead Redemption 1. I think this may be a collection of narratives and entries from Arthur’s journal, along with Jack’s experiences in RDR1. My personal canon for Jack is that after a couple years of gunslinging (and hopefully killing Ross), he finally settles down and begins writing his book. After publishing the book, he leaves his past behind and lives a life in peace, something his father and Arthur would want for him.
