The Greater Good AU
Vox so wanted to go to Heaven during the Trial. He tried all the way up to the portal closing. (He actually got rebounded off the magic of the portal after Charlie and Vaggie went through)
At the very least Charlie tells him that Alastor got his message. (Leaving out that it activated mid-trial when Alastor tried to make his argument for ending the extermination, it was keyed to the voice signature Vox remembered)
Vinelle sent along two letters (One from each) and a painting as "Alastor said he still doesn't like pictures." and Vox gave a watery laugh at that comment and the beautiful image of Alastor sitting at a cafe with what must be a teenaged (Angels Age Slowly) Vinelle.
Vox says something akin to how he missed so many years with his spouse and baby. Confusing everyone, because "Alastor was pregnant when he died", but Vinelle is very clearly a Seraphim.
Essentially, while Alastor was living his human life to past the point he would have contacted Rosie, Vinelle was just an undeveloped soul.
Alastor "felt" her appear shortly after and Vox knew he was pregnant when they met, but was so down to be the father because he loved Alastor.
Alastor was absolutely amazed when he realized Vinelle was still coming once he got to Heaven, it would just take longer because of her unique nature.
Vinelle has little pomme clock hands that mark her cheeks. Red rings instead of circles like Lucifer with short lines that extend up into spade arrows pointing at her eyes. A sign of her powers, different enough that no one ever catches on to her bio-father's parentage.
Alastor never wanted to talk about him.
Her eyes and skin tone are absolutely Alastor's. No doubt in Vox's mind.
Charlie is like 'I'm bringing my girlfriend, not my overlord helper who is good at public speaking and convincing people, sorry! I'll give your husband your message!'
Vinelle's soul appeared shortly after, but biologically she's both Lucifer's, AND Vox's, cause she needed a body and that required Alastor having sex with Vincent.
That being said, Vincent being fully willing to not just be the father who stepped up to Niffty but also Alastor's unborn baby is adorable, and Vinelle not asking about her bio dad because she knows Alastor doesn't like talking about him is also adorable, so we can make that an au of the au!
There's an art proshippper did of Vinelle, where she actually has both Alastor's brown AND Vincent's green blue heterochromia, and blue hair tipped with pink like Alastor's angel form - I love her having the little clock symbols on her cheeks, wings like Vox's in Vox dei, he looks at the art of her and is like 'SHE'S GOT MY EYES AND BLUE HAIR!!!' and cries.
Vincent is clutching those letters and painting and getting all teary eyed, while also crying about how old she's gotten he's missed so many years!
Charlie: uhhh, Vox? how come your husband is a four winged archangel and your daughter is a seraphim?
Vox: SHE'S GOT HIS NOSE!!! *sobbing* WHAT WAS HER FIRST WORD?!!! *more sobbing*
