i feel like there's a lot of loose ends we're not going to see wrapped up because of the one year gap. Sure, we'll have the aftermath, and they might be summed up in a memory or dialogue, but it's not the same as being there as it happens. Seeing the expressions on their faces, so to speak.
The thing reaction shots I was really looking forward to seeing was what happens after Jasnah finds Ash and Taln. What Ash's reaction to waking up in (I assumeh) Urithiru is. What Jasnah has to say to her. How Jasnah breaks the news to Dalinar & co that she has two Heralds in custody, would they like to interview them? (Would they recognize them? Some of them saw Ash and Taln during the battle, but it was pretty busy and there was evil mood lighting).
