Hi Sheldor -Thanks for checking out the audio. I was doing this on a laptop in less than ideal conditions, so I was concerned I had missed something.
I agree with your Sabrina correction. I don't edit posts as a rule, so I can't correct it in the original post, but I will add it below.
As for who says the "we have to think of another option" line, it was hard to tell who was saying it from the audio alone, but Christina's lips do actually move during that exchange. It is hard to tell on individual frames, because of the shadows falling on her face.
