He was in that strange and mysterious realm known as the pre-retcon timeline.
If Kiara will still be a cub in TLG (I am not going to consider a few images of her as solid evidence that she will be a cub in the show), then we can kiss TLK continuity goodbye even more than after TLK 2 came out, or 1 1/2 for that matter. With TLK 2, you can in the end argue that "Fluffy" from the first movie is in fact Kiara, even if the two look nothing alike. With TLK 1 1/2, you can argue that as a parody, it's not supposed to be completely faithful to the story. After all, Timon and Pumbaa are watching the movie in a movie theater. Where did the find it? The Pride Lands? I didn't see one in any of the wide shots of the area...
But for Kion to be in the events of TLK 2 (when Kiara is a cub and later), not having him be in TLK 2 would be a significant plot point that is never mentioned. Not only would it be a fall-back plan for who gets the throne should Simba be defeated, but he was never mentioned as being on the hit list either.
So there is only 2 possibilities:
Either TLG does in fact take place
after TLK 2...
Or TLG was created after TLK 2, and the team behind SP were not aware of any future plans of the TV show. But who am I kidding?
