Joel , Tess , and Ellie head outside the wall to begin their journey to the Capitol Building. The two wonder who Ellie is, Tess theorizing that she is "some big-wig's daughter". They proceed through the underground tunnels dug under the apartment building, reaching a ladder that leads to just outside the wall. Tess has Joel go first to make sure everything is clear. They notice a patrol in the distance but proceed anyway. Ellie briefly remarks that this is her first time outside the wall. The three proceed through a truck only for Joel to be surprised by the soldier, detained and the trio subsequently captured.
One soldier orders her subordinate to scan the three for traces of infection while she radios to command. Tess tries to bribe them but is told to shut up. A nervous Ellie attacks a soldier as he scans her, stabbing him in the leg. She tries to attack again but is knocked down, the soldier preparing to shoot her. Luckily, Joel reacts in time, tackling the soldier to the ground. As the two struggle, Tess shoots the other, the latter having been distracted by her comrade's conflict. After a brief struggle, Joel wrestles the soldier's gun from him and kills them.
As the three catch their breath, Tess notices the scanner that soldier had been using is bleeping. Upon checking it, it reveals that Ellie is infected. Joel and Tess round on her to explain, but Ellie claims the bite mark on her arm has been present for three weeks, despite the infection typically turning the victim into a Runner within two days at most.
Joel doesn't believe it, claiming that Marlene set them up. Before they can act on this, more soldiers show up, so the three must flee the area. They sneak past several soldiers in the trenches but are met with another patrol. Knowing that there are too many to fight off, they escape the wall perimeter through the sewers as the soldiers are called back.
With time to think, Joel and Tess discuss their options. Ellie explains that her immunity could lead to a cure. Joel is against completing the mission while Tess seems hopeful at the thought of a cure. Joel tries to dissuade her from the mission, reminding her of the Infected and hostile survivors. Tess understands but is reluctant to change her mind. Tess and Ellie begin to walk to the Capitol Building, leaving Joel to follow.
They proceed through downtown Boston and reach a large chasm, which forces the three to enter the partially-collapsed Goldstone Building.
As they pass through the unstable building, they encounter a number of Infected, including Clickers. Tess explains what they are to Ellie while Joel forces the door open. Once through, Joel is tackled to the ground by a Clicker but is saved by Tess, who shoots it dead.
They push on, finding a patrol of soldiers that had come through the same building but were killed by Stalkers. They climb a wall, evading Clickers by throwing bricks and bottles to distract the creatures. They reach the other end of the building but are met with a large group of Runners; Joel must eliminate several of them so that the group can pass safely. Once done, Tess commends Joel but he shrugs her off. The make it to a subway station, finding dead Fireflies and a Molotov Cocktail. They find a note that tells them they aren't the group they should be meeting. After bypassing several Infected, they exit to the streets.
A wave of Infected chase Joel, Tess, and Ellie into a building. It turns out to be a museum still containing a number of exhibits. Tess and Ellie crawl through an opening that collapses, leaving Joel alone as Clickers appear. He makes his way through the museum to find a Runner attacking a door. Inside he finds Tess and Ellie in trouble, as a number of Infected are attacking the two. After a short fight with numerous infected, they finally clear the area of Infected and continue to the roof.
The Capitol BuildingEdit
Joel, Tess, and Ellie reach the Capitol Building, but find a dead Firefly near the perimeter. As they enter the building, they find that all the Fireflies are dead and Joel and Tess argue about what to do next. Tess frantically searches the body for a map or directions to the lab that Ellie was going to. Joel argues that they are taking this too far, that they should just go home. Tess then reveals that she was bitten. She shows Joel her wound and remarks that it is already worse than Ellie's, although she was only bitten an hour ago, while Ellie’s is three weeks old. Tess asks Joel to take Ellie to Tommy because he will know where the Firefly lab is located. Joel protests, but Tess asks him to do it for her. She says, “There’s enough here that you have to feel some sort of obligation to me.” Before Joel can answer, the military shows up and Tess sacrifices herself to give Joel and Ellie some time to escape into the subway station outside the Capitol Building. They pass through the subway, encountering several flooded sections before leaving Boston behind for good.
