I would like to see similar to what Mac said about his spiritual powers and such growing, but also more so of the fact he begins to accept his destiny a bit more. Yes I know it gives him lots of character in AO and AE being sort of a clutz who doesnt really have a choice to not be a messiah. But maybe we can see a different side of Abe, as he grows older through his journey, and basically more accepting in his role to save his people.
Just a thought of course.
