Pamela Wake

My take on why she left was that she was an abused wife. She seemed terrified of her husband who was calling her repeatedly. Perhaps he also was abusive to the kids who were left with him and continued to be abused. She may have been suffering from alopecia or some kind of hair loss disease, and that's why she wore the wigs. It could've been from stress. She started acting weird perhaps because she had immense guilt about her decision to leave her kids. It started with her pumping herself up in the mirror, like she was trying to make herself believe she deserved the life she had. It would've been nice to have more background story about the first family, but this is my 2 cents. Abused people often abuse others. Serial killers and others who commit hate crimes have been abused. Some movies just like to leave you guessing. It's interesting enough to me to watch.
