Jasper had searched for his sister, met Kiara and befriended her, and even dodged a crocodile during it all. But right from the point that Kiara persuaded her father to accept him, the King distrusted him greatly. He was different, and so Simba couldn't see the point in letting a rogue lion into the pride, partly because only 2 lionesses there knew absolutely anything about him, Kiara & Vina. And since those two get crazy ideas sometimes, he really was not pleased. He reserved judgement for several days, letting Vina catch up with him and Kiara get to know him better. But because of his laws of nature, Simba got all his lionesses, and all of the kingdom, to come to Pride Rock. Kiara was not pleased at all to hear her father say "Exile!", and went through the lionesses that blocked her from stopping Jasper from leaving. Vina wasn't happy either. She just found out her brother was good after all and actually hung out with him for once, and then her 'best friend' exiles him! Her own brother! Meanwhile, Jasper was already far off, upset and confused. He stopped to look back at the Pridelands, then, close to tears, turned around again and walked away.
