if you talk to breezekit with the cast on breezekit will say secret dialog
edit= the cast is not needed you just have to talk to breezekit multiple times
I wrote down her other dialogue (Dialogue not about you and your mother looking different. Also I don't remember all the dialogues word-for-word so correct me if I get any of these quotes wrong!) "Mossball looks kinda dangerous... I'm happy playing with the feather I found"// "You know what? We're pretty similar too! We look similar, and we both don't have fathers!"// "You know Duskpaw? He's Bramblestar's son. I want to grow up to be an awesome apprentice like him!"// "I heard the other apprentices are going to be warriors soon. I hope not. I wanna train with them!"// "We're gonna be friends forever, I hope?//
