I have already made a blog post about this, but I decided to make it again because last time I made it, it got little attention because I made it so late at night, and I think this is an interesting topic to be discussed.
I know this has been mentioned before, but I thought I would bring it up again anyways. When Rick, Michonne and Abraham met Paul in Issue 92, Paul mentions that the Hilltop does trades with two other survivor groups. I imagined one of them would be The Saviors, but then again the Saviors kill people from the hilltop and steal from them so I'm guessing Paul isn't referring to them, but if he is then there is another group close to the ASZ and if he isn't, then there are two other survivor groups, who we haven't met. Now that Rick realizes how big of a threat Negan and the Saviors really are, do you think he would get Paul to bring them into the battle against the Saviors? Hopefully we will meet them soon. Preferably as soon as Issue 104.
