More SPN x HH au
1, Lucifer still makes himself fun-sized bc when he wraps his arms around Alastor his face is DIRECTLY in that chest and he can gently motorboat them 🥴
2, Charlie Morningstar is a Nephilim sired by an Archangel, and her existence is basically a Crime in heaven's eyes so she's strictly confined to Hell for the time being. Which, like, sucks for her since her parents are out skipping around earth all the time, but also this keeps her from being straight up slaughtered because she's "too powerful" or whatever.
3, Alastor at some point is going to tell Dean (and by proxy Castiel) "I do not have the mental and spiritual fortitude to deal with your bisexual drama right now." Sam is going to find this hilarious.
4, Gabriel's going to love Alastor. Lucifer is trying very, very hard not to be overly possessive when he finds out how much his younger brother is cozying up with his wife. It's fine! Everything's fine! He knows Alastor is 100% loyal to him and Gabriel WOULDN'T even think about stealing his wife so everything's FINE!
5, Castiel and his brothers in arms sort of already know that something is up with Hell from when they went down to "raise Dean from perdition." After Alastor's reorginization of Hell, it much more resembles Hazbin's idea of Hell than it does Supernatural's. Human souls are left to wander around and basically torture each other rather than there being demons doing the work. Of course, Castiel and his soldiers don't really care about this and only truly give a shit about accomplishing their mission, which they of course do.
6, No one really knows who tf Alastor is besides Lucifer. Lucifer is the ONLY person in existence who knows about Alastor's origins. No one knows how a (seemingly living??) human in Hell started interacting with Lucifer through his cage. No one knows where his abilities come from. No one knows how he became the Queen of Hell. You can't even tell from his soul what exactly is wrong with him, because again, he's a multidimensional celestial blindspot and he can CONTROL how he's perceived.
Lucifer is extremely smug about the fact that he is the only person in the know.
Just had a thought, what would happen if some idiot demon or other villain didn't recognize Alastor and Lucifer, and flirted with Alastor in front of Lucifer? I mean, I could see Alastor not shutting that shit down immediately only if Lucifer is there to witness (he has a fun snack otherwise), just because he finds Lucifer's possessiveness very attractive.
I think Lucifer would sit back and let Alastor have his fun unless Alastor seems like he'd enjoy a show. I'm sure after over a billion years (taking into account the time difference between Hell and Earth) the two are extremely familiar with each others' cues and can easily indicate to one another how they want to deal with things, so it really all depends on their moods. Sometimes Lucifer just snaps his fingers and explodes a filthy little shit, other times he sits back and watches with heart eyes as Alastor disembowels a bitch. SOMETIMES they both put on an elaborate circus torture show for one another.
The couple that elaborately tortures people via circus acts together stays together I guess? Lmao
I figured they'd be pretty secure, just thought it would be funny for the Supernatural gang to see the guy who normally fucking EATS people who don't stop flirting with him all of a sudden start to...well not ENCOURAGE it but certainly not DISCOURAGE it...until somewhere in the distance angry circus music is heard...
