You're a werewolf, at first you thought such a secret was better hidden for everyone's sake, but since Gale opened up about the orb in his chest with you, you decided to tell him. Gale is your panther and the first one you decide to trust with that information.

He's surprised by the fact you've been a werewolf this whole time, though he's very open minded about it, he might start reading books about lycanthropy to understand you even better and be able to help you to his fullest, he loves you.
