Following the end of this week's shopping task, all of the housemates were back together in the main house when a tennis ball flew into the garden.
The group were quick to spot the bright yellow ball amongst the green grass but not quick enough to get outside before Big Brother locked the doors.
Attached to the ball was a message and as Big Brother lowered the blinds on the garden windows and the housemates tried their best to read the few words.
"It's got Dexter's name on it!" Sophie exclaimed, "It says 'Don't worry Dexter... something.. will go..."
Dexter insisted: "I'm not bothered to even read it."
Charlie suggested: "It might have said 'Don't worry Dexter, so and so will go on Friday."
While Jack felt the whole incident showed just how low they had come in the house: "Do you see how excited we're all getting over a tennis ball?!"
