23. Abigail Roberts
The entire finale revolved around Arthur getting Abigail, John and Jack out of the gang and away from the Pinkertons unscathed, with the epilogue catching up with them living a new life. The friction between Abbie and her husband means this newfound freedom is short-lived though, and she takes off with Jack until John can pull himself together.
He does eventually embrace his responsibilities, and wins Abigail back in a tender sequence where the two go on a date and get their photograph taken. The game ends with the family peering over their new ranch but, sadly, that happiness isn't going to last.
Red Dead Redemption 1 sees her (along with Jack) being held hostage by the Pinkertons as a means to get John to hunt down and kill his former brothers in arms. Form there, she watches those same men betray her husband, and dies off-screen a few years later, leaving Jack to fend for himself.
