How was Pip feeling when Jaggars forced Molly to show her wrist to his guest?

We are nottold how Pip felt at that moment, but we can infer that he felt as if his reaction was being measured or possibly censured by Molly herself.

When she held her hands out she took her eyes from Mr. Jaggers, and turned them watchfully on every one of the rest of us in succession.

While he said these words in a leisurely, critical style, she continued to look at every one of us in regular succession as we sat. The moment he ceased, she looked at him again.
