Since Gwaelur mentioned that he plans to return to the Lonely Mountain after this adventure, Bitur will accompany him for the journey back, and spend the next few months before the party reforms firing up his old forge and getting back to smithing. He will also spend a lot of time regaling the children with his latest adventures, and will work on getting the music box working. (He should be able to procure some precise clockwork gears in Erebor, both for the music box and for spares.)
He also will extend an invitation to anyone else in the party who would like to see the lonely mountain and hasn't had the chance. Otherwise, he wishes all good luck and godspeed until they meet back in Gondor for the next adventure.
