"Okay, so, from there, either Lung wants to just bait her or he doesn't. If he does, whatever, nothing to be gained. If he doesn't, he has to provide evidence that Rewind's parents are alive, which can come in the form of a recording or be in real-time. If it's a recording and Rewind-the-copy can't convince Lung to provide real-time evidence, also nothing to be gained. If it's real-time, either he'll produce her parents in person or he'll use some form of remote transmission."
