What if Scar raised Kovu (part 2)

Hi everyone! I come back with this story/AU again. In this, I wanted to make Kovu a bit ruder than in the original movie, as Scar and Zira's training should have make him colder and more agressive. Simba is still protective, but he knows he also had his own problems with the past, so he gives Kovu a chance and accepts him. Meanwhile, Scar asks Zira if all went fine, and as Zira confirms, they start dreaming about their return to the Pridelands as King and Queen (in this AU Kovu is more like their "toy" to make them rulers, Kovu would be King when Scar dies). Later at night, Kiara goes to talk with Kovu and acknowledged Kovu's help back in the fire, but Kovu's tongue is sharp to the princess. Simba goes out to see if everything is ok, and Kiara tells Kovu to hunt together the next day, which the lion accepts. Kiara just wants her old friend back, and try to make the others see (and Kovu himself) that there is some good in him in the bottom. The next morning, Kiara and Kovu reunite and they go to hunt. Kiara teased Kovu and "hunted him", but Kovu was smarter and avoid the princess' "attack". Later, Kovu tells her that she is very noisy and teach her some of his skills. Kovu notices birds and tried to show Kiara how to hunt, so he goes to action but ends "hunting" Timon. The meerkat thought he was going to be eaten but Kovu just ignored him. Kiara approach them and asks what are they doing there, and Timon explains about the birds and the bugs. Timon says that they need help with the birds, and Kovu and Kiara chase the birds out. When Kovu just started to feel fun, notice Scar in the distance, meaning that he has to continue his mission, so he avoid the others and goes to find Simba without explanation. Kiara is worried and doesn't understand what is happening, so she (and Timon and Pumbaa) follow him. Not much later, they find out that Kovu is following Simba and they alert him from the distance. Kiara goes to stop Kovu, and when he tries to attack Kiara Simba runs and attacks Kovu back, giving him the scar. Simba exiles Kovu at the moment, he runs and Kiara, in tears, runs away, worrying Simba, Timon and Pumbaa. Hope you like this ^^ And as always, thanks for watching ^^ I own nothing!
