Several characters grow in self-awareness and tolerance as story plays out. Addison learns that being part of a pack is less a matter of biology than of accepting others, relating to them on their terms. So she gains a better understanding of her own needs. Zed falls victim to the kind of prejudice he suffered from humans before recognizing the need to look past stereotypes. Change is difficult, but through patience and understanding, strong relationships can overcome any differences.
This sequel follows the movie Zombies.
