Well, they could be behind-the-scenes type of side stories.
For example, I would love to see Aida's experiences and feelings/thoughts about her first pumping by herself, and future ones with her fast, ever-increasing production (As a side note: I absolutely love it that the nurse instructed Aida to empty herself whenever she feels full, when she shouldn't do that in reality, I think). Other side stories could be with Aida after she no longer works for Alice, and after each ultrasound.
(Also, hi, this is my first post in this community.)
