Ghost was always the type to keep his personal life private from his teammates, but they were curious about the famous girl who was Ghost's girlfriend. He told them he didn't want to embarrass himself.
Until Soap insisted so much that Ghost agreed and told them the girl's job was unusual. When they arrived at the mansion, some men bowed to Ghost, calling him "Grand Master," which Soap found strange.
Soap: Why do they call you that?
Ghost: It was her order.
Price: Well, that's surprising.
Gaz: How exciting.
When they went inside, the girl's assistant greeted them and bowed to Ghost, not just out of respect but... fear?
Soap: She's afraid of you.
Ghost: She's not afraid of me, she's afraid of her.
Assistant: Miss is waiting for you in her office, Mr. Ghost.
