Very interesting theory. My guess is it would be chromium not bendalloy. I wouldn't say it's such a stretch that the unmade can alter time, but this theory is definitely interesting.

Regarding Rock becoming a stonewarden, he pretty clearly seems to be Kaladin's squire. When Bridge Four joins the battle in Thaylen City, Rock mentions "Kaladin is close." "Ha! I feed him. But here, today, he fed me. With light!" (pg. 1184 in hardcover). This implies that his power comes from Kaladin. It also mentions on the next page that he launched into the air shortly after hugging Renarin. Can one become a radiant of a different order after becoming a squire?

Faded hair did it for me

I don't see how there's doubt on this one. Let me list off the hints. 1) explicitly says not from Roshar 2) Her hair faded to grey and then back again in shadesmar 3) scars seems faded in shadesmar 4) trained by Zahel who is likely Vasher (nightblood says vasher is training swordsmanship currently) 5) has a sword that seems to be a new and improved nightblood (hinted by shardblade like qualities, doesn't have a spren, leaves victims grey, and has some sort of sentience) 6) says that her purpose on Roshar is to recover nightblood 7) says she gave up royal position and says had a history of being too open with strangers (trusting denth) 8) requests bales of cloth to be cut into certain shapes on honorspren ship. I may have missed some but i think it's pretty clear that Azure is Vivenna.

There has to be something special about the chains in the soulcasters because when Shallan's gets cut, repairing the chain did not successfully repair the fabrial.

I agree that about her awesome where she brings out the best in people like her crew of deserters and with Elhokar. I think her character is seriously psychologically messed up and the progression of her multiple personality disorder was written unbelievably. I wouldn't say she's my favorite character, but I love the complexity of her personalities and i think the character development was consistent and deep. Brandon's character development in general is unrivaled in my opinion.
