Is this his real sister?
To prevent him from getting Laurent's phone number, she actually came running over in the middle of the night!
So that night, Lilian arrived and used her own phone to let the little girl video chat with her mom. The two of them locked themselves in a room and chatted with Laurent. Dave had originally planned to bring them some fruit, but as he stood outside the door, he overheard Lilian complaining to Laurent, saying that their kitchen and dressing room looked like they had been through a battlefield.
Angrily, he turned around and left, not even bothering to bring them the fruit.
The next day, he'd have his secretary find a housekeeper who could come every day to clean. As long as he spent the money, how could he worry about his home not being neat and tidy?
