Okay. While I tooootally understand where you're coming from, I am at this point 100% convinced that Adora is a Vindictive Narcissist -- the kind you want to run away from like you're being chased by a swarm of killer bees. There are different levels of narcissism in everyone, some of which is perfectly healthy (a little self-absorption/ -obsession is natural), and some of which transforms into pathological, behavioral, and abusive.
According to Joseph Burgo, Ph.D., there are in fact five sub-types of Extreme NPD, the worst of which is the Vindictive Type:
Camille is a threat to Adora for reasons that might not yet be apparent to us. I feel certain by now that at the very least, Adora perceives Camille as a threat to her status in the Wind Gap community, where she is accustomed to controlling nearly everything -- the jobs, the events, hell she even controls the law! So. Camille's presence as an investigative journalist who wants to expose the deep fissures of corruption and dysfunction in Adora's sick little kingdom might as well be inviting hell-fire and damnation from her mother. But Camille....doesn't really know...not exactly...how much her mother loathes her. Until Adora comes out and says it. There's no better reason to stop believing, to stop trying, to finally realize, "Shit. This bitch really can't stand me. Screw her. Okay, I guess I can leave and never come back forever baai!" That seismic shift in understanding is a gift. A terribly bitter gift, to be sure, but it's a gift nevertheless. Because Adora can't change and never will. It's Camille who must let go.
Look. My mother died last year very quickly and very suddenly of advanced cancer. And I was on the fence about what to do... make amends? Maybe? Finally? I admit that I was open to the idea, but I had serious reservations that it could ever happen. Then, with her last breath, after I told her that she was the most beautiful woman I had every met, and a magnificent force of nature, she replied, "You....are a magnificent bitch." Then she closed her eyes, smiled, and flippin died.
Know what? I drove away from that hospice a free woman, for the first time in my whole life. And I consider her last words a gift, probably the only gift she ever gave me. My conscience was clear.
