______ has overplayed their hand
Having a traitor at the end that is going to back you is a massive advantage, if you get to a 2v2 situation it's basically over for the faithful.
Charlotte has decided to use Freddie as a gift to the faithful but there's going to be too much heat at the end with her having nobody else to fight her corner.
If Charlotte had recruited Jake, they then could have done this same trick of attempting murder on Leanne but it would have cleared both traitors. They would then have a proper little trio with Leanne being none the wiser and could pick off the rest of them.
