I didn’t get that vibe at all but now wondering whether I missed something. I watched the last episode tonight and that scene in the kitchen you mentioned with the younger girls dad was the one in the trailer, he said to Hayley “Do I know you from somewhere? You look really familiar” and she briefly looked him up and down and then said something like “a lot of people tell me that”. I took that to mean the dad had seen her when watching porn but didn’t fully recognise her, I did not get the idea that the dad abused the daughter at all. But I did find that whole storyline very strange, and wonder whether they cut some of it and that’s why it didn’t make sense? The young girls mother seemed very nervous around her but was adamant that she didn’t want her back in the house, even when the girl returned and talked about moving back in. Also, why was she sabotaging Hayley’s family and why did she tell her child that she was a porn star and tell him his mother’s porn star name to google?
