Did Kayn kill Nakuri?
So, read Kayn's story 3 times now and I still don't get what the last part implied. " He spun it with a comfortable flourish and leveled the blade toward Nakuri’s throat." "Do what you must." Sooooo... Was that a just warning to Nakuri? Did Kayn Kill him? Was it meant to be left to the reader's imagination? Was it Kayn, Rhaast, or Nakuri who said the last line? I'm kinda confused, thoughts?
