It is not dual timeline , but multi time periods , the distinction is not just pedantic , but crucial because of your question actually . Dual timelines became a common misnomer for it . 34 years ago was Dolores butchered the town . In the most recent episode , this was when dolores was at the town , it was unburied , and their were other hosts in it . 30 years ago was when Dolores and William went on their adventure . This was when the town was buried and just the top of the chapel peeked out of the ground . The present was when Dolores was in the town , it was unburied , and empty . what other qualms with the multi time period do you have ? <| sep |> Why did you throw it out there ? <| sep |> Ooh ~! Christmas too ~! You must be an awesome guest D Yes you can do this ! Well done ! !!
