I assume that's the movie? I've just about got the books memorized and def not any line like that there.
There's a line like that in movie only (as well as the character). I've read the books over 400 time too and know that to be true. The Hobbit movie, after all, has very little in common with the actual book other than a very general plot. We can't forget that they added over 40 characters that were never in the book and a number of plot lines that were nowhere to be found in books at all.
I am going under the assumption that Jewel is basing the ideas on the movies. Can't wait to see what they come up with after the 3rd movie!
Of course, since there aren't any hobbits or dwarves (dwemer are not Tolkien dwarves after all) in TES, it would be kind of hard to work them in.
