no, tom's obviously "Doc" Emmet Brown who, being (for all we know) a tolkien fan, got fed up with Balrog-wing, Legolas-hair, and what-is Bombadil debating and went back to middle-earth. he overshot middle-earth the first time, and ended up "before the dark lord came in from beond" (forget exact quote) he then moved forward in time and crashed into a tree that existed at the time. since "this sucker is neuclear" that tree became Old Man Willow. Behold the evidence!
- Doc was always slightly silly.
-He would the hobbits were coming and what to do because he had read the book.

-Goldberry is Clara.
-he talks a lot. The wights and willow did what he said to shut him up.

airtight case, I think!
