I've been rereading, and couldn't help myself. The cherry tree ones are heartbreaking. Mort, as well. After all the reveals in the recent chapters, doing a complete reread is so nostalgic, like going back years to an old friend. Also, everything makes so much more sense. Yet, there are still major mysteries left, even from the very beginning. Tic-tocs! Those seeds that Ysengrin dropped on the visit to the Court!
Edit: two recent ones, 'cause I couldn't resist it either!
