Issue 100 is part 4 of Volume 17: Something to Fear.
The three Saviors that were seen in Issue 99 are complaining about the plan to attack the Alexandria Safe-Zone at dawn. One of them says that he is going to head for an unknown man by the name of Paul, whose group is farthest away.
The Alexandria Safe-Zone citizens are seen praying for their lives. Spencer approaches Andrea while she is keeping watch on top of the wall. Andrea is reluctant to talk to him when he starts to mention her and Rick, possibly thinking he's going to act jealous, but he instead reveals that he's happy for her and Rick.
Michonne and Rick are talking nearby at the van. Rick thanks Michonne for everything, and says they'll have to be on the road by dawn. Rick says goodbye to Glenn, and states that he is happy for him. Rick then begins his shift of standing guard. Negan, with fifty other Saviors, sneak up on the group and subdue a sleepy Rick by surprise.
The Saviors line up the survivors from the van (Rick, Carl, Glenn, Maggie, Sophia, Michonne, and Heath) on their knees before Negan. Negan informs the group that he wants revenge for the dead Saviors that Rick and his people killed. Negan then dictates the terms for the group's survival; everything in the Alexandria Safe Zone now belongs to the Saviors. Negan further states that there is a new world order and that Rick and his people now follow Negan - or die.
Negan then tells Rick that he is going to kill one of the group to show Rick's people that he is in charge. Negan introduces his weapon of choice for the execution: Lucille - a baseball bat wrapped in barbed wire. After a long narrative from Negan about who should be killed with Lucille, Negan randomly picks Glenn as his victim. Maggie panics, as Glenn begs Negan not to kill him. Rick and the others remain silent and watch in horror and cry with bowed heads as Negan smashes Glenn's head in with Lucille. The first blow fractures Glenn's skull and pops out an eye. Everyone cries, looking horrified and angry at Negan. Negan then taunts the still conscious Glenn who reaches out and calls for Maggie. Negan then repeatedly smashes Lucille into Glenn's head, leaving a mass of broken bone, smashed brains, and spattered blood.
Negan informs Rick and his group that the Saviors will be back in one week to collect half of everything in their community. He turns around, leaving the survivors with Glenn's mangled corpse.
