For context, I just finished reading TotES, and I have read pretty much every book in the cosmere except Yumi, Sunlit Man, and White Sand.
Question 1:
I can't help wondering how Hoid knows so much about Tress's thoughts, and what she does even when Hoid isn't around. How does he know what Tress does in her private quarters, or when Hoid isn't there to watch? This story is presumably told from Hoid's perspective, so perhaps he is embellishing (and thus making parts of the study uncanon)?
Question 2:
Where does Hoid store his belongings? This may seem like a stupid question, but Hoid is supposed to have hemalurgic spikes, unkeyed metalminds, Stormlight spheres, metal vials and possibly midnight spores. Where does he store these on his person? He can't be stuffing it all in his pockets. Also, Ulaam stole his jacket, so they couldn't stored in that.
