I would love to have Fawkes back... Me and him were pals :,) I'd also love to see an older Sarah Lyons leading the brotherhood group in the commonwealth. OR, have an older Arthur Maxson from Fallout 3, who is a direct descendant of Roger Maxson, the founder of the Brotherhood of Steel and the last remaining ancestor. On a side note, I'd like to see one character from New Vegas come back, and maybe reference the events that took place.
