Imagine Kaz and Nikolai being penpals.
Imagine Nikolai mailing Kaz the locks David made to restrain the monster to see if Kaz could pick them. Imagine Kaz mailing them back with a note that says “Cracked each one in three seconds flat. They need work.” Imagine Nikolai having David create locks that are just meant to be challenging to pick for Kaz. Imagine Kaz mailing those locks back with another note, one that says “Four seconds. They’re improving!”
Imagine Kaz sending Nikolai information in code.
Imagine Nikolai having his crew keep tabs on Inej’s ship. Imagine Nikolai notifying Kaz whenever his crew had reason to believe that Inej was returning to Ketterdam. Imagine Inej being surprised that Kaz was there to meet her in the harbour, even though her ship arrived two weeks ahead of schedule.
Imagine Nikolai having Zoya grudgingly consult Kaz about strategy.
Imagine Kaz always being able to enter Ravka mysteriously quickly.
Imagine a member of Stumhond’s crew wondering why she always has such good luck at the Crow Club in Ketterdam.
Imagine Jesper noticing that Kaz always seems to be in Ravka during the week of the Ravkan king’s birthday.
Imagine Wylan wondering how Kaz always manages to procure Fabrikator materials for Jesper. (”And, Saints, Kaz, how did you find me Fabrikator blasting powders?! - No, I’m grateful, but these are only available to Grish- Ok, I’ll shut up now.)
Imagine Kaz slowly using the word “Improbable” more frequently.
Imagine Kaz and Nikolai’s friendship.
