If this was genuinely an accident I could see her maybe breaking down at some point and telling a close relative or friend what happened. A tragic accident and panic cover up would probably leave someone traumatised though and this woman doesn’t seem concerned about anything but herself imo.
AS is going through unimaginable heart break, the woman he invited into his children’s lives is looking pretty suspicious right now, he will be thinking over the last few months her behaviour towards Gannon and when she speaks of him. He may well have noticed she treats Gannon differently to the other kids. But that’s no reason for him to have ever suspected she would kill his son. It would only be natural for him to feel guilt, even though he is not to blame. There is no rule book on how to act in this situation in front of the media and police and people everywhere, he could have social anxiety which can make people seem awkward. He’s done nothing to imply that he is involved. He wasn’t even there. He’s living a nightmare right now and it’s all slowly starting to sink in. JMO MOO
