After dinner, Nathan brought the kids to this ice cream shop where in they could enjoy their favorite ice cream flavors.
Nathan had booked the entire place and had placed the road going onto this area be on look down. This was to prevent other people from seeing his children while they were with him.
As mentioned, every time Celine and Mei would bring them to shopping on a mall, the adults would be in disguise and the kids would be wearing hats or cute shades to hide their face.
And mostly, they would talk to the manager before they would come as they already briefed them on what to do when they visited a certain store.
The mall manager had to temporarily shut the area were they were to prevent other malicious and curious people from seeing the kid's appearance.
If it's unavoidable, they would ban those people from taking photographs of the kids or make them sign an NDA. It's up to Nathan's people to track them down one by one.
