The directors watched coldly as Amy continued to beat Mandy, none of them took the initiative to stop the attack. They had followed Mandy to Denmark Residence to cause trouble, but she had tricked them. They were all pulled into the situation because Mandy schemed, so they had a good reason to be angry with her.
The emotions and anger of being fooled with Mandy left them with negative feelings toward her. Even those who had hoped that Mandy was the Denmark family's daughter were questioning their option.
Fred saw that nobody else would help the situation, and he personally didn't care about anything else, so he pushed Mr. Anderson out of the way and then pulled Mrs. Anderson off of Mandy. He held out his hand to help Mandy to her feet.
Mrs. Anderson gained her composure for a moment but then began to scratch and grab at Fred when she saw Mandy hiding behind him like he was her bodyguard.
