Hole in the Wall

Hole in the Wall is a quest in Fallout 4.

Quick walkthrough
The Sole Survivor is tasked with getting the cure from Curie in the secret part of Vault 81. This part of the vault is dangerous, as it contains Turrets and Infected Mole rats. If the player is bitten by a mole rat the character will suffer a health penalty.

Detailed walkthrough
After talking with Erin during the Here Kitty, Kitty quest, Austin is added to the vault hospital. Speaking with Dr. Penske begins Hole in the Wall.

Austin, a boy from Vault 81 was bitten by a mole rat when wandering in the secret lower level of Vault 81 and subsequently falls ill. The player character must follow Bobby Deluca to the secret entrance located in the reactor room. The player character is asked to go into that part of the vault and find a cure. During the investigation, the player character discovers the true purpose of Vault 81, and finds the cure; however, there is only one dose left. The player character must decide - give it to the boy (who is in a coma now) or use it on itself, since during the quest the player character also was infected with the Molerat disease.

Options
If the player character gives the cure to the boy, they receive rewards including the Syringer rifle and a room in Vault 81. As a side effect, the player keeps the disease for the remainder of the game (-10 max HP). *see notes If the player uses the Vault 81 Cure on his/herself to cure the Molerat disease, Austin dies and everyone in Vault 81 blames the player.
