I've wondered this myself. I read somewhere that Mr. Cedar abandoned the family. Did he ever contact Glenn? Did Glenn ever try to find him? Things we'll probably never know.
And Glenn spoke french? As I used to be semi - fluent in French (I'm a bit rusty these days, lol), I find that immensely cool.
I'd love to see a picture of 3 year old Glenn on his parent's honeymoon...I bet he was adorable!
