#3. What will Negan think of Maggie’s message?
Maggie wanted to fight an eye for an eye with The Saviors after receiving a message from Simon on the road where they killed one member of their group and threatened to kill Jerry of The Kingdom as well.
Using the captives being held after the assault on The Saviors satellite compound, Maggie used the coffin she got from Simon to gift wrap one of the zombified members of his team and delivered it straight to The Sanctuary.
Upon opening the casket, Simon recognized the person as one from his outpost and immediately wanted to deal with the situation himself. However, Negan said that he has already sent a team out to check on things and he should step down.
Right now, Negan is taking the message very seriously. But it may have lit a fire under Simon, who used his aggression to wipe out every single member of The Scavengers except Jadis and then lie to Negan about what happened at the meeting.
