So Kaladin tells Dalinar that he won't get back in time and Dalinar says "its ok, I can send a spanreed, Szeth can write". What would he have done if Szeth couldn't write?

Would Kaladin just have had to carry some random scribe with him for the entire book?

Would he send Lyn with him? That would be awkward, both because of their history, and because Lyn was initially annoyed at getting hired as a scribe instead of a team member, so now she gets promoted to... sky scribe?
