Hoffrigg feelings in this chili because okay sure it’s fun to imagine he’s just some guy at work who’s shown to share the same sorts of views on justice and suddenly he’s just out here like come be a serial killer with me baby but Hoffman lonely and grieving all alone all of a sudden unable to face old friends and clinging to work as sole source of human connection… staying behind late because home will never be the same (even if he didn’t live with her any place in his life would have been changed), eyeing the jigsaw case with morbid curiosity - anything to get other morbid thoughts out of his mind - over and over again until the obsession shifts to jigsaw’s twisted sense of justice…. yeah that’s a whole other post and I had drafts about it a few months back but my point here is Rigg stayed behind with him, kept him company made sure he’d go back to his own place… Just generally looked out for him
