Yeah, but at least in this case, it doesn't matter. If you don't recognize him, fine, the story still works. If you do, you get a nice bonus.It's bloody irritating, is what it is. I'm rubbish with names at the best of times, so to have a character turn up for me to think 'hmm, isn't that? Ooh gosh, what's his name? Let's dig through the previous books to double check."
But yeah, it's a nice little nod to a character otherwise.
My personal favourite irritating moment is
Spoiler AFFC :
We hear that Catelyn's brother Edmure doesn't like singers, because one of them once made fun of his alleged impotence. It's implied later that this singer was Tom o' Seven, the musician Arya meets at the brotherhood without banners.
It took me a few rereads to figure that out.
