It was recently announced that Station 19, the latest Grey’s Anatomy spinoff, will end with season 7, which will certainly impact the larger universe that the series is a part of. Why Station 19 is ending with season 7 hasn’t been officially disclosed by ABC, but the early announcement allows the show to end on its own terms. Station 19 first premiered in 2018, with Grey’s Anatomy character Ben Warren expanding the universe from Grey Sloan Memorial Hospital to Seattle Fire Department Station 19. After years of Grey’s Anatomy and Station 19 crossing over, the connection between them appears to be ending along with the spinoff.
