I did keep waiting for it to tie in to what was happening in the Physical Realm. I thought maybe Dalinar going to Tukar, which is where the honorspren fortress is in Shadesmar, would tie in somehow. I think we got a little spoiled by the events of Oathbringer in that regard. Still, it will have big implications in the next book, obviously, and luckily everything else was so damn good that I don't mind too much.
