Jonathan returned to LA, and the first thing he did was instruct the housekeeping to pack up Catherine's belongings neatly, even though he had never touched them. She had chosen to stay at his place for most of the week, despite their sleeping separately.
Some men, once they achieve success, disdain their families, and thus the dramas of affairs and extramarital relationships play out incessantly in the world. Others, like Jonathan, come to realize the importance of family after achieving success.
Especially after the recent attack, where he nearly lost her and their son, he increasingly recognized her and their son's importance to him. He resolved to spend more time nurturing his relationship with them in the future, whether out of love or not, fulfilling his promise to them.
