"You want me to do what?!" exclaimed Hermione, staring at the mysterious man. She looked him up and down, losing herself to her thoughts. Who could this man be? She spaced out, lost in her mindscape. She was rudely awoken from her reverie when the mystery man snapped his fingers in her face. "I said, put your time-turner into that socket right there." He pointed to a small outlet on the control center that was just the right size and shape for Hermione's time-turner, the small hourglass on a fine golden chain around her neck. It had the power to send her back hours in time, and she was not about to hand it over without an explanation. Especially to some man who had just appeared in the great hall.
"And why would I want to do that?" she shot back snarkily, cocking an eyebrow at the man. She couldn't believe that she had actually been idiotic enough to get into his… what was this "building"? It was some sort of magic, because it was bigger on the inside. But Hermione had no idea what it was.
"Because, the rotorin in a time-turner allows it to store, in a memory log, any and every important even that happened during its use. Even an event so small that most people would think it an insignificant detail. Because every choice you make affects the whole universe. And your time-turner is particularly special." He said, looking deep into her eyes. "Moving past the part that I have absolutely no idea what a rotorin is, why is my particular time-turner so special? I've just been using it to get to my classes all year, but nothing else." Said Hermione, her curiosity piqued.
Sighing, the man gave her a sideways glance. "I'm sorry, but I can't explain it all right now. But if you put your time-turner in there, I can look into its memory log and we can go back and help Harry and Ron." A split second went by before the man realized what he had said, and then he clapped his hands over his mouth. It wasn't supposed to happen like this. She wasn't supposed to know. But she might be a bigger asset then he originally thought.
