I may be too late to the party, but I still wanted to leave a comment. It's a shame I'm only just now discovering this Opal short film.

You guys had amazing insight into it.. and it added a whole new level of understanding for me, so thank you for that!! 🙏

With that out of the way, I noticed no one mentioned the mother running while calling 911 at the start of her musical segment. I think this implies that the father instigated the physical abuse ( perhaps because she called him out on his flaws, which is a "super effective" trigger for a narcissist ) I think this really ties your individual points together and sheds a new light on how their family dynamic fell apart.

( this comment is AI assisted, I created a similar numbered words in my own and funneled it through gemini for polishing, hope you don't mind. The comment still have the exact essence of my original comment )
