It's a victory IMO, Lisa and David stay, Halfwit and Bea gutted that they stayed, Halfwit and Bea bewildered that Hira left over Lisa. It was a massive shock, and Lisa is very happy right now.
But I do agree that we needed Bea to go, ideally.
Why shouldn't they come to the conclusion it was Vote to Save? I would. They've watched the show before, so they should have thought of it.
Come on, the quietest, most boring one, leaves? You MUST entertain the idea at some point,
