Obviously, this is unlikely to the point of impossibility, but what if it did happen? What if, somehow, Scar or Janja convinced Jasiri that the Pride Landers are hostile and prejudiced towards hyenas (there is a legitimate case they could make for this in general), and that it is neither in her nor her clan's best interests to side with them?
Or what if it happened some other way; perhaps Jasiri finally accepts an offer from Kion to move to the Pride Lands only for Simba to reject her and her family without giving them a chance? She could then become embittered in a justified way and turn against the Pride Landers on her own, and convince her clan to follow her in doing so.
As I said, this is basically certain not to happen, but if it did, how would you respond? Would you reject her turn to the dark side entirely, or go further and give up on the show, even? Or would you give such a turn of events a chance if she were given a compelling reason for her change of heart?
