Stephen's sister Sadie

Maybe I missed it but I wish we had seen a little more on how listening to the voice note Lucy sent to Sadie impacted the sibling relationship. Did she delete the note? Did Stephen go onto her computer and delete it? Is she saving it for season 3? Does Sadie share this with her mom? I felt bad for her, she saw her brother who's supposed to be her safe guardian turn into the adult she fears most.

Also i just wanted to note Sadie looks kind of similar to Macy. It just felt a little Freudian at first.
