I had the weirdest dream ever about the finale. I forgot the main events but I remember at the end of the episode they're at like a huge chess arena, kinda like the one in the first Harry Potter movie. The arena is split into two sides with Cordelia and Fiona inside the arena. Zoe, Queenie and Misty are sitting on one side, as in Cordelia's team, and Madison is sitting alone on Fiona's side. At the end, Madison's move wins and Fiona slits Cordelia's throat and consumes her Supreme powers while the other 3 scream in agony. Apparently, this was an ancient ritual practiced to transfer the Supreme powers to another witch, a one of an older generation.
