Cover the Mirrors
Aaron, Kimberly, and Malcolm were all born around the same time. They all lived together from the age of seven until they were 18. Until Malcolm lost his job at the CMS writing firm, Aaron and Kim were best friends. Malcolm then became more jealous of Aaron's life because he had a good writing career and a beautiful wife. There are mirrors in the room where Malcolm rapes Kim in front of them. Aaron doesn't know, but the mirrors show it.
