Theories about Nuka, Vitani and Kovu

Well, I know we've all got our own ideas, if just like to sure mine.
Nuka: is the son o Zira and Scar. Was born very close to the end of scar's reign.
Vitani & Kovu: twins. Children of Zira, but not scar. Scar was going to have Zira mate with another male, because Nuka was horribly skinny, but got got killed, etc. He had already told Zira his plans for getting an heir, therefor she trained Kovu, not Nuka. Conceived around the same time as Kiara, maybe a little before.
I know this is brief, but I'm sort of just skimming the top of it. But those are the main facts.
P.S. post your own!
