Actually? I think that Nori’s talent is in fact, grifting, travel and confidence trickery. And I don’t think he has ever stopped.
We know from Jed Brophy that before the Hobbit he has been ‘out of Dwarven society’ for quite a while. In Sansukh, after BOTFA, his travelling days are done, so he can’t indulge himself in his favourite pastime quite so readily – certainly he can’t escape his schemes as easily as he used to!
After his death, his main hobby is running a book on any and every event that happens in Arda (for shits and giggles, mostly – what is money in the Halls of the Dead? It’s a way of keeping score, basically).
