I understand what you're saying, but I would also think that High Ones have pretty long memories, and you have to have enough time pass for Timmain to actually forget she was a High One. I would give that a couple of thousand years at least.
True, but I've always thought her changing into a wolf might also have 'cut'/shut down most of her mind, speeding up her 'forgetting' what she was and her friends.
(Thinks of something and looks though OQ 13)
...Hmmm.O_o I kinda wonder if that wolf we start seeing on page 26 is the leader wolf she has Timmorn with.
