Christine smiled slightly at his quiet confirmation, her eyes firmly on him. She would have to try and persuade him to eat something soon. If he wasn't careful he would end up ill and she could not have that. Would not have that. She needed him better and would continue to try her best to make him eat. Make him sleep. There is only so much she could do, he is stubborn after all, but she could try. For now she kept her left arm hooked through his, resting ever so gently on him.
"I am glad to hear that," she told him as she looked around as they walked in. As long as he was happy so was she. The production had been good and she could not really pinpoint anything potentially wrong with the show. And he would not have shied away from telling her if he was disappointed by what he saw. He liked perfection too much to keep it quiet.
She noticed his stare and followed his eyes, quickly dropping them when she saw what he was looking at. She did not look long enough to see just what was happening but she noticed the closeness of the men and then, of course, Enigma. She may not feel very insecure about their relationship now but that didn't mean that she felt happy seeing him looking at her. She may have been kind to her after her accident but she also did not trust that she would keep away from Erik even now. Especially since they had not even mentioned the engagement to anyone yet.
So Christine remained quiet and let him watch the group. She could not stop him.
