Thorin is a book nerd and while on the whole, that is admirable we think he might have been taken-in by the beguiling world of pulp and ink. This is was most famously demonstrated when he went to Chile and climb all its mountains looking for Smaug. He left, dejected, with a passel of confused and bemused Chilean mountain people in his path.
He returned to St. Cloud, the only place that would accept a guy who changed his whole look to emulate a Dwarf-king. Now he sings and plays locally but this is also a feint to hind his true talent; twisting knobs which cause people to make good sounds.
