Phosphophyllite, who followed along, clears the fog with their hands at the sound of Rutile's voice. Then, Guest comes into view.

Dialogue Example Even you, the excellent one, seem anxious about my potential! I look perfect, pretty, and full of energy! I'll find you something much more fun than night patrol...!
Dialogue Example I'm... waiting here to be taken away. Don't be ridiculous! What about the fun? You said you'd find me something fun to do!
Dialogue 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.
Dialogue Example You... what were you doing!! What are you thinking! I'll turn even your worries into powder.
Dialogue Example I don't deserve respect. I'm just good at running away, and before I knew it, I became the oldest at 3,597 years old. Now... I can't even remember why we fight. They said they disappeared, even though they shouldn't have been able to move with those new legs.
