Shardbearer

I wouldn't put any significance to the fact that Nightbloods physical form doesn't move when it's cognitive form does in the CR. You can go into the CR, find the bead of a sword laying forgotten in storage, carry the bead all over Shadesmar, manifest it, and the physical sword won't be affected at all. Also, the aluminum sheath might not have a separate bead because he now sees the sheath as part of himself, so even if it wasn't part of his original construction it's now integrated into his Identity. Now, I think Nightblood is going through alot of changes in WaT. Talking to honorblades to learn new abilities? Developing what seems to be more of a conscience and becoming more self-deterministic? My gut reaction while reading was that his consciousness was expanded after consuming the power of a Shard. Or at least what was probably an insignificant amount of power compared to the Shard, but was a glut of investiture to Nightblood.

Oh I caught the crumbling archs somewhere around day 6 or 7 maybe. Didn't even notice Kaladin's new stone in the epilogue .

Forget the Mandela Effect. It's the Ruin Effect now. changing movies , books, Monopoly Man's monocle...

Well the foreshadowing was already mention in RoW after Shallan recovered those memories. Pattern acting like a new spren that was just pulled into the CR. Pattern saying he wa sure she'd kill him, but then saying they'd send a replacement. Mainly those, and then I saw people posting about describing different colors for her blades. Some of your points are good though, like why Testament didn't scream or why she wasnt there for their first trip.

Theres enough foreshadowing that I think he had 2 shallan cryptics planned at least since WoR.

Well he can manipulate Connection so probably he can Connect himself to Fortune or whatever property atium uses to see into the future.

These flashbacks weren't nearly as emotionally charged as the others but I did appreciate how they filled in some of the details leading up to the Everstorm and return. I wasnt really clear before on how Venli could have met Ulim before Taln broke. I figured Odiumspren must have been locked on Braize but seeing that he was actually brought in a gem by a Terriswoman serving Odium makes sense .

I just went back and looked at some of those parts again. I think question 3 he was referring to Dalinar. It seems like he sensed something with what happened with Unity. Can't really be sure though.

She was looking for the heralds. I think it said Midius drew them if I remember correctly. Midius is another name for Hoid/Wit. Not sure on question 3. Maybe Nale?

I think that these WoB's are saying that spren will be repelled by hemalurgy, or the type of person who would use hemalurgy in this way. I don't think Brandon is saying spren will be repelled by a bond to another spren, as you seem to be implying.

If he's writing the prologue does that mean he's done hammering out the outline?

I thought the same thing when I recently reread OB.If she was hunting Vasher I assume she would have went with the group figuring they could take her to him.

To my mind these 10 people wouldn't be Honor, if that's how it went. They would be... I dunno, Shardlets of Honor? I'm not really sure if that is even plausible. I would guess that with Honor being Splintered it might be harder for someone to become the new Vessel.

Given all the information I know of, I'd say Dalinar's chances of surviving a quite good. I won't be surprised if he survives. I won't be surprised if he doesn't survive. I also won't be surprised if he becomes the new Honor, or if he doesn't. Also MB spoiler: So it doesn't really matter if Dalinar is being built up to take Honor. I know that it's entirely possible that things will get twisted, and that plot twist doesn't have to involve is death. Or there might not be that plot twist at all.
