I really love how the show handles the conflict between Hilda and her mom. As I said, because of the events of s1ep10-11, Johanna became more strict in s1ep12-13, which led to Hilda not understanding this and hiding her intentions from her mom. And Johanna, as any person and any parent, has some flaws, such as her ivolvement with Ahlberg's bells. But I love how in this ep everything she did was right. She let Hilda go despite already suspecting she's lying and then gave her the chance of explaining herself. Yet Hilda ignored that chance and refused to communicate with Johanna when it was admittedly really easy to do. And I feel like that's why Johanna grounded her. It's just like the song at the end says, Hilda doesn't learn from her mistakes, despite helping others to do so.
