So, at the end of the book, team Dalinar/Kaladin has Szeth's honorblade. Who do you think is going to end up with it? No obvious answers spring to mind.
Bridge 4 seems like they're already going to get Windrunner powers through their connection with Kaladin.
Adolin, not being bonded to a spren seems like an okay candidate, but the Honorblade wouldn't work while he's in plate, and that's one of his main assets - being a Plate and Blade duelist.
Dalinar, Shallan, Renarin and Kaladin are all Radiants with their own spren/blades. Wouldn't stop them I guess. Kaladin could bond with it just to keep it safe, but it seems like a wasted resource.
Who's left? Navani? Shen (I forget his new name)? Man, Shen with an honorblade might be a force.
