I understood she brought tedros back as a fuck you to her team who were patting themselves on the backs thinking they were geniuses. Plus assuming she is twisted to further humiliation of tedros, who is now her obeying play thing.
I would assume further seasons would have been her and tedros finding talent and furthering power in the music industry whilst they each scheme for who is in control.
My girlfriend is a materials scientist specialising in non-stick coatings.
The first time she came to my house, I had to throw away all teflon with even a scratch on it. She said once the surface is broken it will leach chemicals into your food.
She said they are perfectly safe whilst the coating is in tact and uses non-stick pans herself. Just replace them as soon as you notice the surface is broken.
