The Traitors [UK]

The obvious snag for a second series of The Traitors is that the new contestants have seen the first one, and thus are more schooled in how to be duplicitous snakes plotting to stab a colleague in the back while smiling into their face. (Why on earth didn't they set it in Westminster?) The question is, will a sequel of the series nicknamed the Highland Hunger Games be weaker because the wannabes know too much? At this stage, frankly, it's hard to tell.
