>A strange knight appeared, and three of the kings were locked away
So, combined with the newly revealed fact that Jevil was the one telling King about the Knight, this basically confirms the Knight was the strange someone who talked to Jevil, right?
The kings were locked away because Spade King suddenly decided to overthrow them out of nowhere, and this only happened after the Knight showed up, who Jevil was responsible for telling King about? And Jevil only went crazy after talking to a strange someone? Sounds to me like they're the same.
