I get the feeling that the writers felt they needed to fill a whole episode, instead of cutting season 2 down to 8 episodes. Not only was this episode cringeworthy, but absolutely pointless. I could understand if they were going to carry on with the sister story, but they weren't, thus making the sister completely pointless, and using it as a "filler" as someone else has mentioned. It reminded me of an old CD album, where you get a bad song to fill the track list numbers. Totally cringeworthy acting, episode plotline and a waste of Millie's talent. And the outfits!!!! This then leads back to why these cringeworthy punks were at the beginning of episode one season 2. But still absolutely zero point of needing it.
