Regarding the second question, want to give us any hints about foreshadowing we have missed? Some fans claim all of the possible theories have already been discussed... total BS. For example, I posted a theory on Threpe a few weeks ago that no one had thought of.

The appearance of both Bast and Felurian change when they touch iron. Would this happen with all Fae or could some Fae fully maintain glamour while touching iron?

Would Usnea’s Chandrian sign of decay be suppressed in cold weather?

Naming relates to the sleeping mind... does shaping relate to dreaming?

Could the act of traversing the greystones be described as a pagan ritual or dance?

Kvothe’s gram is described as having iron, but Caudicus’ guilder is described as having lead. Is this a difference between grams and guilders, or can either be made with iron or lead?
