After Nani and Lilo's parents lost their lives in a car accident, 19-year-old Nani was left to try and take care of 6-year-old Lilo. Holding down a decent job and taking care of a child while grieving a major loss is no easy task, especially when that child is also grieving, but Nani tries her best.

Lilo is too young to fully understand what her sister is going through, so she doesn't go easy on her, doing things like trying to keep an alien in the house. But that alien, Stitch, is exactly what their family needs to heal from their loss. 

On the film's 20th anniversary, director Chris Saunders even opined on the themes of Lilo & Stitch showing up to acclaim in another Disney film more than a decade later. “To be clear, I think Frozen’s’ great,” he told the New York Times. "But it was a little bit frustrating for me because people were like, ‘Finally, a nonromantic relationship with these two girls,’ and I thought, ‘We did that! That has absolutely been done before.’”
