Mark Summerset

Markus William "Mark" Summerset is a resident of Vault 81 in the Commonwealth in 2287.

Background
Mark is an elderly resident of the vault, running the Sunshine Diner with his wife, Maria, whom he has been married to for over forty years. However, Mark's help at the canteen mostly consists of taste testing, and he occasionally attempts to slyly procure more food from his wife, which leads to playful banter between the two of them. Mark believes that the people of Vault 81 are overworked, and, like his wife, he sympathizes with Overseer Gwen McNamara, as she is often blamed for the problems in the vault. He is saddened that most of Vault 81's residents are not interested in helping with the diner, and are more focused on other repairs, but his wife is optimistic that Austin Engill will take the reigns one day. Although he appreciates a good sense of humor, Mark does not tolerate disrespect of one's elders.
