Hmm they sure know a lot. On live feed they are talking about the pool going past the "wet" wall. And they are saying things like we need to get the key because there is a keyhole in the eye.

They think the shutter goes up to reveal the other side of the pool to the other house.

Pre informed?

They know that "guys" are going on on friday.

They havent been in hiding like we're told they are all actors.

Thay know? How many do thay seem to think are going in?

Only 1 is so their wrong.

I dont think it is so much to look in to. Friday is the usual eviction night, so maybe thay know somthing would be planned. And with no men in the house i think it is pretty obvious
