From the plaque at the front door of the mansion, Laina realized her entourage was still in there. That gave her a sense of relief. But just as she was about to openly enter through the main door, she realized what a horrible decision that would be.
Knowing Margaret, she would have thought of a plan to cover up her disappearance while trying to find Laina on her own. That means the other members of staff likely did not know that Laina had in fact gone missing.
Just then, the main door swung open. In a state of panic, Laina quickly ran off to hide behind the corner of the building. She kept a keen ear, hoping to gather any information she could get.
A pair of maids walked out through the front door, carrying woven baskets in their hands. They were chatting and whispering to one another as they walked away from the mansion.
