Because they know that not many people would vote for Sam in the final. More votes is more dosh for them. That's why they keep putting so many housemates up for eviction rather than just two. People, nowadays, are more inclined to vote for a certain person rather than voting each week between whoever is up.

They've got back more than what she is worth from stealing from the winner's prize fund anyway.

They were colour coded so Danny could remember where to place them on the table .Silver nearest Jack , Red to Chloe in the middle and blue for Sam

Its a great possibility.

I also looked at psychological influences. Sam was wearing a blue dress that matched the blue envelope. This may have been designed so that she was naturally drawn to this envelope containing £15K with the thought that this would likely see her evicted against Sam and Chloe and their corresponding £1K and £10K.

It's an interesting theory but I think Sam would have gone no matter what the question to be quite honest.

The twist was tacky and lacking tension but it got rid of a useless housemate so I don't really care

They did effectively. BB would know housemates favourite colours. They get to know everything about them before they enter.

They new which housemate would go for which colour. Classic Uri Gellar type mind reading fix.

The pack of envelopes someone from Production bought from like Tesco probably had different colours in :laugh:

So Tesco fixed the result. No wonder they are shutting stores. Can't get anything right.. :laugh:
