Complete story — includes the ending
The strangers reveal themselves to be Henry and his younger brother Sam. They form a tentative truce with Joel and Ellie and together prepare to escape the city. Ellie and Sam quickly become friends while Henry confesses to Joel that he was responsible for the death of Kathleen's brother, Michael. When Sam developed leukemia, Henry turned Michael over to FEDRA in exchange for medication. After escaping through the tunnels, the group is attacked by a sniper, who calls Kathleen. She arrives with her militia to kill Henry, but a horde of infected emerge from underground, including a large "bloater". Kathleen and Perry are killed while Joel's group escapes seemingly unharmed. However, that night, Sam shows Ellie that he was bitten on the leg. Ellie uses her blood to try to cure him, but wakes the next morning to find Sam infected. He attacks her, but Henry puts down Sam and takes his own life. Devastated, Joel and Ellie bury them and set off for Wyoming on foot.
