Of course he did. He started to understand a lot of things in general, and that can't help but make me glad. KaneDom in pt2, imo, changed dramatically, stopped being stupid (which happened to him from time to time before) and became much more proactive and attentive to details.
Kane started thinking strategically and learning from what he heard and thinking ahead...Not to mention his dramatically increased assertiveness and skyrocketing confidence in himself and his right to "be first among equals". We finally got the KaneDom we deserved from the very beginning of the game. And from what I've seen, I get the impression that the Karlssons decided not to wait until after the game show and decided to prepare KaneDom in advance for the M-->Z1 stage.
