I still find it odd though that the reception girl says she wont be on the island but Joy will be on the island and message me to play poker.
Joy explains this, she does not want to be disturbed unless deemed relevant or of interest, to her.
That the player wants to distrub her is irrelevant, he's just an enjoyable lab rat in her maze.
He is her tool, she is not his.
Oh sure, she will make sure the maze is running and if she is in the mood check the mercandise too. But that's just business and having some fun on the side (sex, poker, whatever strikes her mood).
But at the end of the day she will do what she want and head back to the real world.
Which in itself signals her unique status, she is the only person who can come or leave as she pleases.
So Joy could be sitting on the reception desk reading a book and the answer would still be she was not on the Island.
The receptionist is simply acting as any personal assistant would.
