I must admit, I'm actually kinda happy they didn't do anything about her MK9 ending. So many people theorised Jade would be manipulated by some divine being to do her bidding, and I just didn't want that to happen. They could easily have made it be Cetrion or Kronika, having Jade being their minion - which Revenant Jade was! But past Jade was what saved her character for me in this game, and she's the one we got to play in Story Mode. THAT's the Jade I like!
I was admittedly also very worried when we found out that Jade and Kotal would have something going on between them, but I actually like how they dealt with it. Instead of having Jade just go from "Kitana's friend" to "Kotal's lover", she was presented as her own individual character with her own strong personality and sense of self, where Kotal was just another connection added to it. Very tastefully done, imo.
I would actually love to see the timeline continue, to see what would happen with Kitana on the Outworld throne and so on, but I'm also glad that this story is kinda a "fix" for the whole Revenant thing which I was never really a fan of.
I see a lot of people not liking the story and how it turned out, but I for one really enjoyed it.
