Before the first cut she is torn between staring and revulsion, wondering if her 'colleague' is feeling any pleasure or simply fighting for life. She can't look at it and she also can't look away.
After the cut, she stares straight ahead acting nonchalant and pretending not to watch as her eyes dart back and forth, stealing furtive glances and the degradation of the gal she met on the doorstep an hour before.
In the final third of the clip, it's her turn and her eyes are shut tight as she tries t imagine that if she can't see the camera, it's not really happening to her.
Or maybe I'm just projecting.
