I dont get it
If Kovu never met Scar then howcome Vitani can remember him
There'ry the same age are'nt they??????

I think there's an important question to be answered
before:
HOW MANY MONTHS (OR YEARS) SINCE SCAR DIED
UNTIL KIARA IS BORN??
May be it wasn't much time, so
Kovu could have met Scar just being a little older than
Kiara.

But here's MY theory : Nuka was
supposed to be Scar's heir, but Nuka wasn't what Scar
expected, so Scar told Zira that her next male cub would be
his true heir. Shortly after that, Scar died, and Zira had
to mate another lion to keep her promise. In other words:
Kovu had been chosen even before being born.

Actually, Kovu's a good sum older than Kiara because Kovu
already had some of his mane growing and even when they're
older, he seems alot wiser than her. I doubt Kovu met Scar
but all the same they pretty much said that the last born
was the Chosen One. But then again Zira said "He was
HAND-CHOSEN by Scar...Kovu was the last born BEFORE you
exiled us to the outlands" So it is a possibility that they
did meet, but Kovu didn't remember him. But surely it
would've been a while before Simba came to the conclusion
that Zira and the others needed to be exiled. But it also
wouldn't have been that long before Kiara was born. If it
was a long time to exile Zira, then Kovu would've been alot
older (and bigger) than Kiara. So if Kovu did meet Scar, it
was probably for a very short amount of time between then
and Kiara's birth.

Funny thing is Vitani and Nuka knew him. I think they
actually remember him. But in the deleted scenes in the
LK:SP Kovu acted like he didn't know Scar. But Nuka always
acted affectionate and hyper whenever they mentioned Scar.
But Vitani was always sarcastic and layed back when they
talked about Scar.

You know, the outlanders where supose to be part of Mufasa's
pride, until they were banished with Scar. But Scar died by
the Hyena's attack. So, these lionesses where here before
Scar died.

And true.. They are generally
pictured as the same age. But in real life, lions and other
animals dont care about it. So it doesn't really matter.

And animators dont look at that.

Well This is just a theory on My part, But I don't think
Scar was killed by The Hyenas. So He could have seen Kovu,
But I doubt Kovu was old enough to Remember Him.

Kovu is Zira's son and Scar said it was to be Zira's last
son who was the chosen one

Scar met Kovu before he died around the same time when he
made friends with the hyenas. He was kind of a rouge lion,
and with all that time probably met a heck of a lot of other
characters if he wanted to!!!
