Re: The Official "The Hobbit" movie thread *SPOILERS*
That makes sense to me.
I believe that the trolls that are basically slaves/warriors/work horses are those that just dont talk and are not supposed to...they are meant to and are trained for business only...Bert,Tom and Billy basically have no master and are just chillin out for the last few thousand years...probrably escaped from Morgoths Army after the fall of Gondolin or the final battle with the Valars forces with leftover treasures from Gondolin and now talk up a storm like 3 good buddies do...Pals and mates for life...JMHO of course but it's how I interpreted it from both the books and films....Trolls were meant originally dumb but poerful servants when first created by Morgoth
That makes sense to me.
