If I was a producer...
Jake and Liberty are looking rocky tonight
Brett and Priya decide they are better as friends.
Brett (whose heart rate was raised the most by Liberty) starts chatting to Liberty. A lot. She starts to feel better about the rocky situ with Jake.
A new girl comes in so it's boy's pick next. Brett picks Liberty! Jake fumes but what can he do? And as a producer I want to make fuck sure that no one else comes in with a £2 set of bracelets, a strip routine and a gameplan so I am going to be sure Jake has to stick around with either new girl or Priya and watch Liberty cruise to victory!
Liberty doesn't have to fall for Brett in 10 days. She just has to be with anyone else other than Jake to win.
