Ms. Rosa

Ms. Rosa was a resident of Sanctuary Hills in 2077 prior to the Great War. Post-War, she has become a feral ghoul by 2287.

Background
Ms. Rosa was once a neighbor of the Sole Survivor. When the effects of the Great War hit Massachusetts, she and her son 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 place, she tried to use the fact she had a child as leverage, but that failed and they were left 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 she still roams the Commonwealth and Boston alongside her son.

In a terminal entry she is mentioned as a customer of a chem dealer who lived in Sanctuary Hills at one point, buying Buffout from them. She was also a widow and was restoring an old Corvega with her son.

Other interactions

 * Ms. Rosa can be found as part of a random encounter with several other ghoulified pre-War citizens.
 * The encounter with Ms. Rosa 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
Ms. Rosa appears only in Fallout 4.
