So while looking up Madam Pince I came across this:
Click to read why Madame Pince = metamorphmagus = Emmeline Vance = Mrs.Severus Snape? Which sounds ridiculously insane but reading it actually makes sense! Obviously it can't be canon but it's a brilliant example of how seemingly non important details can be brought together to make a passable theory.
I'm such a sucker for conspiracy theories though. If I have evidence presented to me like that with detail and explained well then I can really get into it. But I guess I'm the sort of person who always thinks the worst of everything and thinks there's always a hidden meaning or ulterior motive so it plays right into satisfying that part of me.
I want to know what he thinks of her attraction to Filch o_O
