Jack and phryne kiss
I know many fans find the final scene of Blood at the Wheel very hard to watch but I still rate it as one of my very favourite scenes, not just for the absolute perfection with which Nathan and Essie play the scene but as much for the importance of it in the development of their relationship. Having watched all of season 3, it is clear that this was a pivotal moment in the development of the Phryne and Jack relationship as it stands by the end of the third season. Jack is clearly unsettled by the realisation of the depth of his feelings towards Phryne and the fact that, in his mind, she continues to use and abuse her relationship with him.
We learned that before becoming this independent, strong, and confident Lady Detective, she was once in an abusive relationship which scarred her so deeply that she had trouble trusting men or forming lasting relationships since. The source of her suffering, Rene Dubois, came to Melbourne ten years later to kill off those who witnessed him murdering Pierre Sarcelle, and Miss Fisher was forced to face him and her inner demon. The stage was set in a French restaurant; the familiar environment probably added to her anxiety as it reminded her of the days in Paris. He tried to calm her nerves by cracking jokes about the snails on his plate, which rendered little effect.
