I have a theory that Esme Squalor started the Quagmire fire. Esme wears a lot of white and black in the Tv series and she also loves extravagant things and the headdress is over the top. She also owns a spyglass. And will stop a basically nothing to get the sugar bowl. She might of thought that Beatrice gave the sugar bowl to the Quagmires are they were part of VFD and friends.
what do you guys think?
