Mr. Sumner

Mr. Sumner was a resident of Sanctuary Hills in 2077 prior to the Great War. Post-War, he has become a feral ghoul by 2287.

Background
Mr. Sumner was once a neighbor of the Sole Survivor. When the effects of the Great War hit Massachusetts, he and his wife were one of many in the panicked rush to Vault 111; they were denied entry by Vault-Tec staff and armed soldiers. Realizing they were unable to secure a position they begged the Sole Survivor to try and get them in, meanwhile they were helpless outside the gates to the vault. Despair eventually set in and they would swiftly find themselves in the midst of nuclear devastation. They survived but underwent ghoulification and ultimately became feral. 210 years later he still roams the Commonwealth and Boston alongside his wife.

Other interactions
Mr. Sumner can be found as part of the Named Feral Ghouls random encounter with several other ghoulified pre-War citizens.
 * The encounter with Mr. Sumner and the other ghouls can repeat, even if the Sole Survivor has killed them previously. These ghouls will level up with the player character, and may even change from one type of ghoul to a stronger type with each reincarnation, making them potentially extremely dangerous. They will always spawn together and re-spawn sporadically, meaning that even if the Sole Survivor falls to them in battle, defeats them, or if one simply reloads a prior autosave or quicksave, they won't be in the same place.

Appearances
Mr. Sumner appears only in Fallout 4.
