Guys i think i understood what's going to happen in the end of issue 102 negan will come to the safezone and at issue 103 Rick will surrender to Negan that's why it says: " Rick Grimes is no longer in charge, and nothing will ever be the same again" because Negan will be in charge. At the description of issue 104 it says "If you won't handle this... I will." that means that Carl will stand up against Negan (possibly with Andrea and other ASZ citizens, maybe with Hilltop's help) therefore handling what his father could not handle. Don't you think this makes sense? Oh and sorry about the grammar mistakes
