Raoul arrived at the Opera House and found Madame Giry. She told him she had no idea where the "opera ghost" had gone. All she knew was that he was missing and she had promised to tell Christine when he came back. He left, glad to know the truth and furious to know that Christine came back for him. He went home and heard Christine crying. He went to her and saw her crying, the crib next to her.
"Christine what's the matter?" he asked, truly worried.
"It might be his."
"What?"
"The baby might be his, Raoul! I'm unfaithful, but I have to know."
"Christine, promise me that if you find him, if Gustav is his, let him take care of the child and we can have another one, ok?"
"Oh Raoul, are you sure?"
He still didn't trust the man, but knew this was what he wanted. "Yes."
"I will then." She knew it would be hard for her to part with him, but also knew it was the right thing to do.
