Jin stared at Lilly as she walked. Her question didn't really make much sense to him. He tilted his head in confusion as he followed after. Was she talking about his abilities? Course, if he said something wrong, would Lilly take it the wrong way? He didn't answer or say anything, as he was still pestered about the question. Were they on the topic about mating? That thought crossed his mind as he watched Lilly carefully. "I... don't know..." he said finally, now following Lilly side by side. "What do you mean by 'Fast or Strong?'" he questioned.
