I'll be the first to admit that I believe trust issues when it advance to Ryan Murphy's shows,particularly American Horror Story. So much information gets set out there, but not all of it is true. That's why when Murphy first started talking approximately a crossover season between Coven and Murder House, or I all but rolled my eyes. Having said that,Murphy seems like he has an actual procedure for this to advance together. In an interview with Entertainment Weekly, he divulged some details approximately his vision:"It's a character from season one that will be thrust into the world that you are left with at the end of Coven, or which is sort of like the male/female/witch academy,and then all of those characters will intertwine, which is confusing because some of them are from seasons one and three. Like, and Sarah Paulson will probably be playing 18 characters."Paulson better clear her schedule! While we do know this won't be season seven,AHS has been renewed through season nine, so Murphy has plenty of time.
