It's true, they can't mostra every little detail about crucial plot parts in a film. But what they can do is refer to everything crucial. Like, in this case, if there had been another cub before Kiara, they could've and would've detto so in the film.

Nala: "She's just like te when te were young."
Simba could've replied...

I know some people think that Scar and Mufasa are not brothers but te see they are and I will tell te SCAR: Scar has his mother's pelliccia she has brown pelliccia and he has his father's mane he has a black mane and also Scar's green eyes come from his father too!

Okay, so some people wonder who Scar and Mufasa grandparents are well.. here te go Scar and Mufasa grandparents are (DRUMROLL) Mohato and Asali! Now...
