Despite Lennox's suggestion to move his siblings to a new school in Jinling, Adrienne decided to return to Chiangshi in a few days. It wasn't because she was against her husband's idea but because she felt his siblings would need to adjust again in a new school with new classmates. Adrienne didn't want them to lose friends they already had and disrupt their academic progress.
Lennox allowed them to return home, but he couldn't help but worry about her. However, he didn't want to stop Adrienne from doing what she wanted and confine her at home, as Alistair did to her in the past.
He wanted to return home with them, but his hectic schedule at the company forbade him to do so. He also didn't want to inconvenience his siblings by transferring schools, and he agreed with Adrienne's point that they would lose contact with the friends they already had at their current school.
