I reread your canon-divergence story for Expired where Charlie and Alastor get summoned and I was thinking about how different it would be if it happened in double entry. With Alastor in heaven, he could be the one to calm down Lucifer.
Honestly, I daydreamed a whole mother-verse idea Alastor and Lucifer come down together because Lilith got summoned with Charlie, and Alastor looks at them and is like "Darlings, that circle prevents demons from leaving or entering. You, Charlie, were born to an angel and a human, and Lilith, you literally never died. Neither of you are demons. You can step right out of that circle."
And this Angel Alastor has spent like 10,000 years being bored in Heaven so while he DOES prevent Lucifer and Michael from slaughtering a guy on live TV, he would be like "punish him in a way that feels like a nightmare to him, but for outsiders watching, looks like entertainment. Give the kids at home a show!"
And Lucifer, dressed as a literal circus ringmaster, is like "OH I know EXACTLY what to do!" And just reality bends everything so that they're now in a circus tent, the cultists are dressed up like circus performers, their masks are gone, and the hostages are sitting down in nice seats watching the show as Lucifer begins announcing the performance. Gabriel getting behind the cameras like oh I gotta make this a cinematic masterpiece, this looks like it's gonna be FUN.
Lucifer picks up head cultist Vox by the ankle and flies up into the sky, and is like "Alright folks, for our opening act! Watch, as I guide my not-so-lovely and unwilling volunteer, blindfolded through three dangerous trials! First, the path of snakes! Presenting a path teeming with some of the most venomous animals known to the living, such as the Black Mamba, the Boomslang, the King Viper, and more!"
"Second, the den of jaguars! Now, I know lions are a classic, folks, but do keep in mind that jaguars have the strongest bite force of any wild cat on earth! Not only that, unlike lions, they're solitary and independent hunters— I imagine they're not too thrilled to be stuck together in the same cage! All my volunteer needs to do is walk in, feed each individual jaguar, and walk out!"
"And lastly, our final trial is simple! I'm sure you've all hear of this one before— the tightrope! Forty feet high, no safety net, and blindfolded, my volunteer will need to hold a pole with two filled water buckets on either end, and walk from one end of the rope to the other without spilling! Here's hoping he can keep his balance!"
My daydream ended with Vox falling on the third trial, and when he hit the ground, the ground transformed into basically a bounce house floor and he just sort of bounced a couple times while screaming his head off. Confetti popping into the air the second he met the ground.
I was just enamored with the idea of Lucifer punishing these murderous cultists on live television for the world to see (in a child-friendly way because the first man asked him to,) and it's just a genuinely fun and exciting circus performance for the people watching, while being a genuine psychological nightmare for the cultists.
I love this. This is absolutely what would happen, Alastor and Lilith and Charlie and Emily and Sera and Adam and Cain and Abel and Eve (yeah, Cain is in heaven in motherverse and so is Eve because that's the good timeline okay I don't make the rules Alastor saved them all from themselves) and Michael and the other Seraphim bar Gabriel who is broadcasting the whole thing and also the Exorcists who have never been to a circus before and they are eating popcorn and peanuts and drinking sodas and so is Jonah cause Alastor found them and got there in time to save him because no dead kids in my fics and they're having a great time.
The cultists are not having a great time but nobody cares about them.
Lucifer swings between being the ringmaster torturing Vox and the cultists and being the magician with the sexy assistant (Lilith) who calls for an audience member (Alastor) and they flirt wildly with him as they cut Vox in half, and then they go back to the circus acts. Alastor and Emily and Charlie get to pet the jaguars, and with Alastor there they are able to have Jonah pet them too.
