I was just thinking about Madam Hooch. Something about her in the first film really bugged me. More specifically, her eyes. They're yellow. And kind of cat-slit. But...why?
Then it occurred to me. Is she an animagus?? My roomy suggested that perhaps she is an owl.
I know that JK said she had seen things in the first two films that we would know about later, but could this be one of them??
