Revenge of the Rulons - S1.E2

Yungstar and Serena bring an injured Stegosaurus back to camp. He's one of the only dinosaurs that doesn't run away when an earthquake hits and severely cripples the Dino-Riders' defenses. Gunner and Tagg's attempt to corral their dinosaurs causes Llahd to be captured by Rasp. When the Rulons' ultimatum is delivered to Questar, he implements a plan that gives the Stegosaurus a chance to help save the day.
