For Eve!Lilith!Alastor and Roo Rosie-
The reason why Rosie dresses and styles her town in Edwardian style is because that’s when Eve ‘died’ so to speak. Roo, while came into existence after the bite of the apple, didn’t have a form until it felt Eve die and formed Rosie. Rosie would then reach out to Alastor to make their deal to drag their beloved follower back into hell, keeping her claws so tight around his soul Heaven nor Lucifer will take him away again
Also maybe Rosie herself even took the place of Lilith for a while (effectively destroying the Morningstar family) so no one realized that she was missing. This was not to help Heaven however, this was just so she could get Eve all to herself.

I love it! Now we know the Exterminations started seven years ago and at the same time Lilith vanished, I actually really like the headcanon I came up with that forced reincarnation HURTS a soul, so it feels back in time to use the presence of its whole self as a sort of splint to grow, so Rosie/Roo is using Edwardian time because that's the time Alastor was BORN.
Here's my headcanon for how it goes down. The Root of All Evil exists, and is let in by Eve eating the apple, and in doing so it becomes sentient, conscious, and takes the name 'Roo' - but it's still trapped.
Until Eve/Lilith is forced to reincarnate and suddenly her soul is in two places at once, and it allows a bit of Roo out into hell, where she takes the name Rosie and sets about befriending her beloved Eve in the form of the Queen of Hell, while also preparing for Alastor to come to Hell and the moment the Stable Time Loop will close.
She's so, so happy when Alastor summons her because, thanks to Mimzy calling him an Altruist and his victims victims praying for him he's worried he might go to heaven (she takes a look at his soul and he's right to be worried) so she doesn't even ask for his soul to get him to Hell, she says she wants a task and will even put a time limit on the task of a hundred years, after which if he hasn't completed it he gets his soul back, provided he DOES attempt to fulfill the task. Alastor, who just really wants to go to hell, is like 'sure, that's fine, its a deal!' and they shake - and then to make sure nothing could possibly stop him from going to hell she makes sure he dies the day after.
The task?
Remember who you are. Remember your past life. She doesn't want to own his soul - she wants him to love her, to be with her willingly, to free the rest of her from the Pentagram Moon that it is trapped in and for them to rule Earth Heaven and Hell together.
And until he does?
Don't you forget - you are my PET.
MINE.
