Do you think Kovu ever confessed to Kiara about the plan Zira had, and the role he himself played in it initially?
Or did he just choose to not tell her?
In the movie, Kovu is quick to abandon Ziras plan and fall in love with Kiara (who firmly believes he`s a good person who would never harm her or her father) but he is also seen practicing telling Kiara the truth, he just doesn`t get the chance, as Simba interrupts and takes Kovu out for a walk of the Pridelands, at which point the ambush happens, and you know the rest.
I think Kovu has a good heart and a kind nature, he`s not a villain, but a pawn in Zira`s game. It`s a little messed up to think about how Kovu would have attacked Simba and tried to kill him if Kiara hadn`t showed up when she did (for the hunting lesson Kovu had promised her). Kovu never attempts to attack Simba after this.
So do you think Kovu ever came clean about this? I personally think Kiara and Simba would deserve to know the truth, but on the other hand, what really matters is that Kovu was never evil and he never acted on Ziras desires. So if he did tell Kiara, do you think it would ruin their relationship, or would Kiara be forgiving? Kovu had after all been trained and brainwashed his whole life by Zira, and the change of heart he has proves his good nature.
