Ok, when I found out that Kiara is a cub in The Lion Guard I didn't like it. Don't get me wrong. I am trying to make myself get used to the idea that Kion is a cub, not to mention the same age as Kiara according to what Disney just said. Yes, he is the second born but maybe he was from the same litter (making kiara and kion twins). So yeah.. he was born after Kiara and as it turns out he is the same age as her (not a big fan of that either).
By the way yes he is the second born because -for the last time- there is no Kopa! :P
However! It makes scenes from the second movie not make any sense!...
