Back in 2020, FX renewed American Horror Story through season 13, so there are unlimited options for future seasons and new timelines. Ryan Murphy tweeted a poll earlier in April 2021 for fans to vote on potential themes for upcoming seasons and it came down to Bloody Mary and sirens. While Red Tide was set by the sea, it would be interesting to see an American Horror Story season set entirely in the sea. That could feature another blend of modern-day and ancient timelines. Additionally, Ryan Murphy could go another route and introduce more period-specific pieces, like seasons set solely in the '70s or '90s and bring back more characters from previous seasons. Knowing Ryan Murphy, new and unlikely connections will probably be formed in new timelines, regardless of what upcoming seasons of American Horror Story cover.
