Part of me loves speculation like this, but the other part of me wonders if the speculators are aware that Tolkien (and authors in general) is/are "just another imperfect human". Did Tolkien think of any of this? It's his world. Speculators creating their own fantasy around it aren't really speculating, but making up their own version. It's like the "nerd at star trek convention" finding plot holes. The reality is a staff room filled with writers working under deadlines and restrictions. However there seem to be people who want/need (and speculate) that every possible detail can/should be nailed down into something that makes absolute sense. Maybe someone just wasn't very creative one day, or wanted to move onto a bigger plot point. Anyway, this is just one dude's (me) point of view, maybe the speculators are more imaginative and better at life, and I'm just a cynical old man.
