Sharon is a character mentioned in Fallout 4.
Sharon was a woman who worked at the Vault-Tec Regional HQ in Boston before the Great War. She once spilled coffee on her superior Mr. Davidson, which angered him very much. One day, she mysteriously vanished.
In one of his terminal entries, Davidson says that if Sharon spilled coffee on him again, he would stab her in the throat with his pen. In the basement of Vault-Tec Regional HQ, there is a skeleton behind some boxes wearing a Vault-Tec uniform. It has a pen lying next to it, near the neck. This is most likely the body of Sharon, Davidson hiding her body in the basement.
Sharon is mentioned only in Fallout 4.
