History: 
Casie was a much loved cub from birth, just like her siblings. However from a young age, she noiced Kovu was beginning to grow very hateful towards her grandfather. It made her paronoid and she tried to warn simba about the danger, however Simba never believed her, and Kovu started to threaten her. 

Simba died from old age months later...

Since Kiara couldn't see the hate within Kovu, Casie ran away on her own, towards the elephant graveyard, where she was attacked by Janja and a few other hyenas. Luckily an old outsider lioness came around and chased away the hyenas and raised her as her own, until she was old enough to look after herself again, Grateful for the care, Casie grew to be just as caring as that outsider...
