The Hospital[]

The Hospital section

On the night of April 28, 2034, Joel wakes up in a hospital bed to find Marlene welcoming him to the Fireflies. After apologizing for the bump on the head, Marlene asks how Joel and Ellie managed to find the Fireflies, to which Joel responds that Ellie "fought like hell" to get here.

Joel asks to see Ellie but Marlene denies him, saying that she is being prepped for surgery as they speak. Marlene reveals that the Cordyceps in Ellie's brain has somehow mutated according to the doctors, hence why she is immune. Studying her brain would allow the doctors to reverse-engineer a vaccine for the Cordyceps brain infection, though since the fungus grows all over the brain, Joel figures out that Ellie would be killed, insisting that Marlene find someone else only to be detained by her guard, Ethan.

Foreseeing this, and knowing that Joel had formed a close bond with Ellie in the past year to the point that he would not allow the surgery to proceed, Marlene orders Ethan to march Joel out of the hospital and kill him if he tries anything. Marlene leaves, and Joel, after seeing his backpack, disarms and tortures Ethan to tell him where the operating room is. Finding out that it is on the top floor, Joel kills him.

Alerted by the gunshots, the Fireflies find Ethan's corpse and proceeded to search for and attempt to kill Joel. Determined by the player, Joel evades or kills them and blocks off the West Wing access. On the top floor, Joel finds several recordings, one being the head surgeon's assessment of Ellie's immunity and two others recording Marlene's indecision and reluctance to kill the child she promised to look after. Joel eventually finds the surgery room as more Fireflies guarded the hallway leading to the operating room. After killing and/or evading them, Joel bursts into the operating room, where the doctors were surprised to find him. The head surgeon, Jerry Anderson, tries to prevent Joel from taking an unconscious Ellie by blocking his way but is killed by Joel. Leaving the two assistants to their fate, Joel carries Ellie away as more Fireflies close in on him. He manages to get to the elevator and reach the parking garage but is confronted by Marlene.

Marlene attempts to reason with him, asking how long Ellie can live safely without being eaten by clickers or raped and murdered by other survivors. Joel disregards this, saying that it is not Marlene's choice to decide but unsure if it is what Ellie wants. Marlene allows him to live if he gives Ellie back to the Fireflies and slowly puts down her gun as a sign of trust while walking towards him. Joel hesitates for a few moments, before he shoots her with a hidden pistol. After he places Ellie in a car he walks back to Marlene, who pleads him to let her go but Joel kills her stating "you'd just come after her".

As Joel drives out of the city, Ellie wakes up, wondering what had happened. Joel answers that they'd found the Fireflies. He goes on to say that there were dozens of people who were immune like Ellie and the Fireflies were unable to develop a vaccine from them, to the point that they've stopped looking for a cure. Ellie sadly rests up while Joel takes them back home and apologizes.

Behind the scenes[]

  • This chapter, "Tommy's Dam", and "Jackson" are the only chapters of the game where the player does not encounter any infected. It is also the last chapter that the player controls Joel.
  • Patient eye charts throughout the hospital spell out "run you are nearly there, don't quit".
  • If Joel stays in the operation room with the doctors too long without doing anything, it shows a cut scene where Fireflies come in and kill him.
  • When Joel is running away from the Fireflies carrying Ellie, it is eerily similar to when he ran away from infected carrying Sarah. He also is stopped by Marlene, who threatens him with a gun, just how a soldier did twenty years earlier. This time, however, Joel is the one who opens fire and proceeds to execute Marlene, much like how the soldier would have done.
  • Robert foreshadowed the events in this chapter in the cutscene "Queen Firefly", when he declared that they should fight the Fireflies directly. Tess also remarked that it would be a "stupid idea", foreshadowing how it is one of the most challenging sections of the game because many enemies use assault rifles and body armor.
