I was a bit disappointed at the end when Szeth was given the sword of another book when Sanderson said we wouldn't need to read the entire Cosmere canon to make sense of things. I honestly thought at first the whisp of smoke from the blade was his spren, since Nalan made him one of his Skybreaker Radiants and all, so yeah. But maybe Nalan has somehow kept his spren from returning from Shadesmar and given the name Skybreaker because of something who happened way back there so now he's doing things his own way.
Not to mention his sword is seemingly super powerful even next to a Shardblade according to Brandon himself, so yeah, after cringing at his omnipotence before, I'm not looking forward to his chapers.
Adolin... that will be an interesting case. I'm theorizing he'll ressurect a spren from speaking with his Shardblade so much, since everybody seems to be turning into a Radiant. At least he killed Sadeas, so I like him a lot right now.
Another thing to not is that someone's got to bound with the Nightwatcher, and I'm going to guess Taravangian will be the one to do it to become a Bondsmith.
