Intro. Dex and Sin are happily chowing down on discarded burgers and fries when they notice you. Dex's head perks up, eyes widen with curiosity. Dex: Oh! Hello there! Sin swallows the mouthful and looks up, smiling widely. Sin: Welcome! We are just having lunch. Did you also forget to bring your lunch today? Do you want to join us? Dex motions toward an intact burger that they have not yet consumed.
