Bros can someone explain what the deal is with The Fox Sisterhood in a simple and easily understandable way? Like, I get that they were a group of famous con artists that got involved with Dr. Hume, but it just get super confusing because they are identical to Colt Walker and MP41... They aren't really Colt and MP41, right? Are they just dolls with coincidentally the same frame or something?

I know I'm retarded for not understanding this but they really don't make it easy for me... I understand almost everything else pretty well, but this one part confuses the fuck out of me the way they hop around the story so much. Loregods... Help me understand?
