After reading that email my mind is spinning with possibilities. Grodner said the game starts before they enter the house. What if they are bombarded by fake maids or hotel staff? Trying to get them to spill the beans on who they are & what they're there for?

Something has to be happening to them in sequester since they said the game will start before the house. Could be one of them is a mole & will try to bust the others.

And why are they allowed to make phone calls from the hotel? I thought all contact with the outside world stopped once they got to LA & went into sequester.
