Maybe mac or davey if they keep going with the pattern of having them die and then switching to a character they were close with

Mac and Davey are mentioned so few times and have so little importance in the story, but fans continue to insist that one of the brothers will be the protagonist.

^ Arthur wasn’t in rdr1 at all yet he’s the main character in rdr2

The next protagonist will be Micah Bell IV.

I think I'd like to see either Jack Marston or Mac Callender as the protagonist
