The quest for the water chip nears its end at the Necropolis. The Vault Dweller can show mercy to a ghoul kept prisoner by the Unity garrison by releasing him from his cell.

Enter the Watershed's pump building. After negotiating the way through Harry and his garrison, locate the ghoul at the end of the building, beyond the water tanks.
