Yeah, Broomhilda/Django/Shultz and Ben/Rose/Hannibal are in no way accurate emotional parallels (and "tame, mature"- I agree very much), but the combination of the "married couple plus their friend" dynamic and a vaguely similar setting were enough for me to seek out the fanfic. Which I then enjoyed reading for its own qualities! Plus, I happened to have seen Django Unchained for the first time last month, and so it occurred to me as a potential canon when I was trying to come up with something to read. (I also tried Pepper/Tony/Bruce from the Avengers fandom, which turned out to be terrible, or at least the story I read was, and Sherlock/Watson/Mary, which was not great but not bad, either.)

I love Peter! I am very excited for the new book, particularly because the last one ended on a bit of a cliffhanger.
