You are 100% on to something with this.
Trisha ‘told me’ how it would go on that route. I would hope that you or I in that position would do better than she wants to, but there’s a lot of ignored/suppressed hatred there. Years worth.
The best ending for my money is the Golden Ending (thus why it’s named that way) because Trisha can’t be a fully functional, uncorrupted person while in Jasmine’s orbit, even if she’s winning the competition and putting Jasmine in her place. She needs a clean break.
