Before I get into this, I'm not saying it is happening; just pointing out that situations like this can lead to events that do happen.
I grew up in a small piece of shit town, while I was never in or involved in the system; I went to school with and was family friends with kids who were in the system. One of the biggest red flags aside from basic child neglect where they have to ask what is essentially a stranger for food; is having more and more strangers / "friends" come over at all hours of the day. And when the parents or whoever are burnt out, passed out, and otherwise indisposed of (in the middle of the fucking day of all times), and strange people are in the house with children, children get molested and abused.
Again, not saying this is happening, I am making no accusations against Steel Toe, his wife, or the Rekietas, and I'm not gonna intervene because I'm just an outsider looking in; but I'd be lying if I didn't say Nicholas and Kayla are setting up a bad if not dangerous environment for their children. Because I've seen this shit before and while it may not be happening, it's making that part in the back of my brain say "this isn't right."
If Nick's dad visits again, it should be a with a court order and the Sherriff to take the kids to Florida.
