|The following is based on Fallout Tactics and some details might contradict canon.|
Here, you'll find two super mutants named Jim and Joe Grimm. Joe stands over his injured brother, Jim, after he was injured by a landmine. If the player helps heal Jim, both mutants will later be available in the recruitment pool.
Jim and Joe's personas are reversed after this encounter - the recruitable version of Jim is actually "the brains of the outfit" and his brother Joe becomes a stupid (IN 3) that "likes to bash things and act all masculine".
Behind the scenes
Joe and Jim Grimm are a reference to Jacob and Wilhelm Grimm who are popularly known for publishing a number of German folktales during the early 19th century (Hansel and Gretel, Cinderella, etc. to name a few). In this parody, however, the Grimm brothers are semi-illiterate. Jim says, "Sorry, brother, me stupid." Joe, despite carrying a copy of Big Book of Science and Dean's Electronics (both of which can be stolen), says, "the old Brotherhood would of shot first and asked questions later."
Sometimes after healing Jim, you won't be able to leave the area.
