The whole plot of the first "Brother Bear" was that Kenai had to go to that mountain to become human. But at the end of this movie, the spirits were about to change Kenai back into a human in the middle of a cliff, which makes the entire first movie completely pointless.
When Kenai and Nita are talking after crossing the river, look at the shadows. Kenai's shadow is behind Nita, giving the impression that she has the shadow of a bear. Possible foreshadowing? (No pun intended.).
