Broken down into 4 scenes, each establishing an important part of the story and things to come:
Scene 1 is what gets everything rolling, setting up the overarching story of Blue Star and introducing the characters and their personalities.
Scene 2 is a raunchy, five-minute lesbian sex which firmly establishes Liara as a shy submissive who, once she gets going, really gets going, and Jack as a no-nonsense dominant that nevertheless wants her partner to cum - for her satisfaction of watching, not for their own satisfaction, of course!
Scene 3 further establishes personality and plot, setting up episodes two and three.
Scene 4 is a post-credits scene, and leads directly into the larger, clandestine plot of Blue Star, and leads into episode three (episode two establishes its connection to the clandestine plot separately)
