Has anyone figured out how to do this? I know you can rewind the tape to revert Crystal back, but I'm stuck figuring out exactly how to pass this. 

You have to listen to the entire tape from start to finish. As the tape goes on, Crystal will become overexcited and you’ll need to rewind the tape until she goes back to the first phase of her interview animation. It’s like Milkamean’s interview but a little more lenient seeing as how you don’t have to listen for loud sounds and prodding her forehead or stomach. You just have to keep an eye on Crystal’s movements and excitement/arousal levels until the tape finishes.
