Something that has been considered here before. I tend to think their shared history will be more important that any differences.

When The Walking Dead returns next month, the season is expected to deal with the return of Morgan Jones, a character we have known since the pilot episode, but who weve only seen in a smattering of episodes so far. The season six trailer hints that Morgans rivalry may upset the balance of the group with Alexandria and perhaps even threaten Ricks role as leader.

How that plays out remains to be seen, but before season six kicks off, we thought it would be worthwhile to look back at the relationship between Rick and Morgan to see how the past may inform the future of the series. And what it reveals is that, based on the mirrored events of the first two interactions between Rick and Morgan, its quite possible that Morgan has not shown up to Alexandria to hurt Rick. Rather, hes there to save him.
