It is going to be horrible for me when I'm wrong. I'll get over it quick, I promise.
I've seen that Jim watched lots of Babylon 5 while writing, formulating the Dresden Files. I'm going to need to binge watch it and compare and contrast that show with Dresden Files like I did with Amber series and DF previously. Anyways, in Babylon 5 they have some time travel plot within an overarching story and we do have a WOJ that Jim wants to do something like Babylon 5.
In Babylon 5, Jeffrey Sinclair the commander of the station in season 1 gets transported into the past 1000 years to later become Valen, a Minbari prophet held in highest regard by the Minbari. 1000 years later a war breaks out between Minbar and Earth because a human spaceship mistakenly interprets Minbari warship aggression and fires on it killing its leader. This sets off a war between Earth and Minbar. Just before Earth's fleet is demolished, Minbari fleet takes in a shot up human fighter to test a human. They use a ritual object on him (Jeffrey Sinclair) and it erupts in a great light. Minbar now knows Minbari souls have been reborn into humans. Minbar surrender as Minbari are forbidden from killing Minbarri. This begins the development of the Babylon space stations. Babylon 4 ends up being a station that the past needs to defeat the "Shadows'. It is involved in a time traveling plot as is Jeffrey Sinclair. This brings us back to Babylon 5, Jeffrey Sinclair finishes his command of Babylon 5 for 1st season of the show and then goes off to be an ambassador to Minbari. He of course, as I said before, later becomes Valen in a time traveling plot 1000 years in the past.
I believe we now have another circumstantial piece of evidence that Jim may be planning a time traveling piece back to, in some way, 1000 years ago to when Mab ascended. This may be a parallel to Babylon 5.
It should also be mentioned that Sheridan and Delenn, who I would view as Harry and Murphy, end up with a baby boy David. I'd say somehow Marcone would end up being this parallel David, I'd have to somehow insert him though 40years prior to Storm Front somehow as we have WOJ that suggests he is 40yo at SF.
Anyways, I had this peculiar thought while writing this. I was thinking of Murphy and how she might be able to bypass the Lady restriction on maidenhood. I was thinking maybe she have to do a body switch or something. After all, you are a soul, you have a body. Anyways, it was a side tangential thought but then it led me to Amanda Beckitt and me wondering what is Jim planning for her.
