Teft completed his character arc. It was a good way to go out - great end for a great character.

I'm not sure if Adolin will become a Radiant, or if Sanderson has some other plan for his relationship with Maya. Her speech was really impactful and opened up a lot of interesting possibilities.

It was unnerving to see Hoid vulnerable, but he probably had some plans in place to account for what happened in some way.
