Well to be fair we don’t know about a timeline really. Once isn’t really good at creating a specific timeline. I don’t think each episode is a day or anything like that.
Although JMO did say that it’s been more than a year in S3 since Emma came to SB. I think that’s what she said.
I hate that A and E released this spoiler and you can tell Adam is getting tired of it. He’s not even denying the spoilers anymore or anything he appears to be just about done with the fandom.
Why would any of those spoiler people want to spoil this especially Katrine, she would keep quiet for sure. VCF would but that person isn’t on set every day.
