I used to think I knew it all and then everything needed changing. Now I know the best thing is to contribute, to be part of a team. We're good at that, lions.
After Fleck's mother is killed, he is referred to throughout the film as an orphan. In fact, one of the adult males in the pride would have been his father. He, Linus and the other young males would also have left the pride at sexual maturity, not stuck around and tried to mate with the lionesses (as Fleck tries to do with Suki), who would be their relatives.
