Ellie, Samuel and Leo use the underground tunnels to get to the other side of the minefield. They are forced to run down an un-mapped tunnel after getting chased by werewolves. Meanwhile Amari and Jaxson find a survivor named Connor, who is being attacked by a group of raiders. The two take the raider group out and save Connor. Jaxson decides to bring Connor along on their mission to find Ellie, however Amari is suspicious about him. Ellie, Samuel and Leo safely reach the surface and notice a group of people in the distance. It turns out to be Amari and her new friends, and so the group joins together.
