Thank you all for your kind welcome and your quick responses, BUT....
As Sam Vimes might say, "I wouldn't buy that for a ton of cabbage."
1. Angua's first descent into the mine is with Vimes alone. Carrot's not there. I don't think she "faints" until she's either down there with Sally and Carrot or on the third trip when she finally discovers the bodies. Watertight door--BALDERDASH! If she can "smell" a body two floors below, she can smell through a bloody door, wouldn'tchathink?
2. It didn't appear that Rascal did any real "study" of the battle. He originally went to Koom Valley because it was a nice place to paint, and found the cube in the process. I suppose during the 16 years it took him to paint the painting he might have done some research, but, again, why would he even have thought of the idea of painting the battle unless the cube--whose language he couldn't understand--told him to do it? It's true the characters in the painting are less important than the location, but the popularity of the Codex implied that the figures were quite accurate, down to the kinds of chain mail the dwarves were wearing. Since Rascal was, well, mentally challenged, it's hard to believe that a man being pursued by a chicken would spend a lot of time reading history books.
3. To Tina: And there's nothing wrong with starting sentences with conjunections. But not all the time. Unless it's necessary. Or relevant.
As far as baked beans are concerned, I can't stand the damn things. Now, Boston cream tea, Boston (all right, New England) clam chowder, and Sam Adams Boston lager are MUCH better, if not necessarily accurate, representations of our regional cuisine. Then again, we ARE the ones who caused all those problems for you folks over the pond, so you may take it with a grain of sea salt....
