Right, i've been searching on several notable websites, most prominently the Vault about this cut companion Ulysses. By now many people know that Wolfhorn Ranch was once his, yet he abandoned this life, but i've found a lot of info about him. In Dead Money, the companion Christine says she was rescued by the man named Ulysses, this is indicated by her saying she was rescued by a man (from the big empty) with a flag of the old world on his back, this man said to her that he was searching for somebody else, who I believe to be the courier. He also tells Christine that she should go after Father Elijah because Ulysses knew what it was like to search for someone who had a major impact on his life, i.e. the courier. Also, in Primm, what Nash says is relevant to this. Because Nash says that the courier before the main courier, when he say the couriers name on the list, Ulysses turned around and asked if this was for real, and then left saying, "No, let 'Courier Six' carry the package'. It is also implied Ulysses has links towards the legion, because in the collectors' edition card set, he shares a suit with the legion members such as vulpes inculta, caesar and aurelius of phoenix. Finally, in several of the possible endings for Dead Money, characters here out a "battle at the divide (grand canyon)" between "the two couriers", this heavily implies that Ulysses' hunt for the courier will be abackground storyline for all the DLC, finally culminating in a duel in the final DLC. If this does actually happen (highly likely it will), I think I will personally run up to the head of Obsidian and hug him, as well as give him my house, but yeah, let's all hope this happen, because if it starts out as a background story nobody notices, then starts to grow into a life changing (in game) moment, where everybody is kicking themselves off of not realising it themselves.
