Source plot synopsis — includes the ending
Clementine and AJ are evicted from the school. Outside, they are attacked by Abel and another member of the raiders, Lilly, the woman who either left or was banished from Lee's group during the first season. Lilly attempts to coerce Clementine to convince the other kids to join her group, but she refuses and escapes with AJ, which leads to AJ being shot. The pair are saved by James, a former member of the Whisperers, who tells them the raiders are forcibly recruiting people for a war against a rival community. Clementine returns to Ericson for medical treatment for AJ and to warn them about the raiders. The children prepare the school grounds for an attack. Two weeks later, the raiders arrive and though they are pushed back, they manage to kidnap some of the children and murder one of them. The children learn from a captured, dying Abel that the raiders have established camp in a nearby riverboat and with James' help, infiltrate the boat and plant a homemade bomb in its boiler before encountering Minerva, now a member of the raiders, who imprisons them with the others. Lilly confronts Clementine and reveals that Minerva killed Sophie when she tried to escape their group.
Clementine incapacitates Minerva, frees the children, and fights Lilly into submission, who is then held at gunpoint by AJ. Clementine can tell him to kill or spare her; if spared, Lilly murders James. During the chaos, the bomb goes off and the ship explodes. Clementine and AJ escape the sinking boat as Lilly (if spared) flees on a raft while the other raiders are overwhelmed by walkers. If James is alive, he leaves the group after arguing with Clementine over AJ killing Lilly, potentially aiding their escape, depending on choices. Clementine, AJ, and Tenn meet with either Louis or Violet, who leads them back to Ericson. After reaching a partially collapsed bridge, the group is attacked by a bitten, crazed Minerva, who has led a horde of walkers to them. Clementine fights off Minerva, who slashes her ankle, and crosses the bridge with AJ. Louis or Violet try to make Tenn cross as well, but he is too stunned to move; if Clementine previously trusted AJ, putting the confidence in him to make hard decisions, he shoots Tenn to save Louis or Violet, otherwise, he will tell Louis or Violet to throw Tenn across the gap, thus saving him, but resulting in the other person getting devoured.
While escaping the horde, a walker bites Clementine's wounded leg. Clementine and AJ take shelter in James' barn, which is quickly surrounded by walkers. A weakened Clementine urges AJ to escape on his own by covering himself in walker guts, then asks him to either kill her or leave her to turn. Regardless of her request, AJ swings Minerva's axe at her. Sometime later, it is revealed that AJ chose to amputate Clementine's leg, saving her life, and the two have finally found peace and a home at Ericson.
