Can you help me and summarise me what happened between William B Davis and G&D? I think I’ve lost some passages? 🙏🙏🙏 Thank you!

He basically wrote a book to say how Gillian and David were unprofessional and arrogant. That there was a lot of tension and animosity between them. And then promoted it telling everyone Gillian had done plastic surgery. I don’t know if this idiom exists in English, but in French it’s called “spitting in the soup”.
