Personally, I think it would be awesome is someone made a Joshua Graham (Caeser's first Legate, killed after first battle of Hoover Dam) companion. There was supposed to be one in Van Buren, but we all know the story of that game. Basically a recreation of that character would be great. I mean, references to him living are abound, and even Caesar is afraid of him. A recruitment encounter similar to the one that was supposed to be in Van Buren would be icing on the cake. http://fallout.wikia.com/wiki/Burned_Man
