i cant recall his name, he is my avatar, the man who seems to float between the lodge and twin peaks.... is that Log Lady's husband? just a theory.... more of a question...

He is the Giant, an inhabiting spirit. "One and the same" as the Great Northern room service waiter. He hangs out in the waiting room with the Little Man From Another Place. The actor is barely old now ;)

My theory is that one of the Woodsmen in the convenience store scene in FWWM (possibly the bearded one played by Jurgen Prochnow) is the Log Lady's husband, who we know was a logging man that died in a fire on their wedding night. He would be Margaret's age, I think, at the time of his death.
