I'm glad you said that, about the look on Ron Grantski's face as he is standing behind Sharon and she is making that statement. It was a look of horror. It was clear that he had never come close to seeing her like this, and as a result, he was afraid.
Yes, he did look absolutely shocked but also he showed some fear for Sharon. I thought he even looked like some mist was overtaking his eyes. Anyway, the "look" on his face was really something.
