When I read ADWD the first time I found his existence very frustrating. On top of the fact he does nothing interesting in the slightest, he isn't even an interesting character himself. Literally the most remarkable aspect about him is that he's so boring that's how he's described in the narrative on multiple occasions. The second time I read ADWD, I found myself totally puzzled by his existence as a character with a POV. He has nothing to add to the plot, nothing to add to the cast of characters
