Aayush's father, as expected, does not want Tia in the family. He views her as having no connections, so he set out to eliminate her. Unfortunately for him, Aayush walked in and ended his game. When the truth comes out, things will reveal. While Tia appreciated Aayush taking a stand for her, she felt he did too much. She wants to fight her own fight. She doesn't need saving. She is a strong girl who always took care of herself. Aayush is proud of his girl. But the message did need to be sent to his father. A strong one. That he can not bully Aayush. Aayush holds the actual power, not him. The father got the message but he might still try to damage Tia somewhere.
