Speech Example Even an excellent one like you seems anxious about my potential! I look perfect, pretty, and brave! I'll find you something more fun than night patrol...!
Speech Example I'm... waiting to be taken away here. Don't be ridiculous! What about the fun? You said you'd find me something fun to do!
Speech Example Will you fight me? I want to beat you at what you're best at. I think I've been jealous of you for a long time. It's funny, isn't it? We're both Diamonds, but I'm so much weaker than Bort.
Speech Example You... what were you doing!! What are you thinking! I'll turn even your worries into powder.
