In this one, his last word's are "I finally got your attention, didn't I?"

This makes Zira even more barbaric, in that she didn't take Nuka's last words to heart and realize that she'd just thrown away Nuka's life in her quest to get vengeance on Simba.
Also, it shows that he doesn't really hate Kovu like Scar did (well, kinda, as we never found out how Scar's cubhood was and if Mufasa got all the attention) but it now seems that he made those remarks about Kovu and his dislike for him, NOT because Kovu was the Chosen One and he wans't, but because Zira spent all of her time on Kovu and blatantly neglected him.
In regards to this, I think he WOULD have gotten redemption like Vitani had he lived to the Final Battle.
