My first evidence is obvious the first episode but I'm still unsure if Alastor already knew Vaggi was an angel and that's why he didn't try anything against her
But my tingles were tingling in episode 3
While we know now that Vaggi did her research about Hell to "fake-it-til-you-make-it" and not let herself be discovered, she is very much comfortable here. Alastor too drops the filter in his voice to talk to her about getting rid off of Pentious eggs.
In ep 5, despite it all, Alastor ins't insulting Vaggi here (and technically, he is kind of not letting herself be exposed as an angel). The commentary of the bluray explained Alastor here was flexing for Lucifer to see (lmao)
These are more crumbs but I know there's something to be said about Vaggi being able to use Alastor's radio to hit Lute on the face
And Vaggi was also happy to see Alastor back at the end, the only ones making bad faces were Husk and Lucifer
On season 2 we got less of their interactions but (if only once). BUT! I feel they are meaningful
They were bickering at the beginning of episode 1
And he is not exactly mad at leaving the spot for Vaggi to handle the hotel (when he was making a whole fuss about it in season 1)
Then in Hazbin Guarantee, Vaggi is the only one who calls him "Al". That sounded a lot like "Dad, please, behave".
In "Silenced", she keeps calling him "Al"
And I know this was more of tauting Lucifer, but, c'mon, it has only been a month and a few weeks
But for me, it was settled that they are close because of this shot
You CAN NOT tell me that's not a face Alastor wouldn't do. The closer you are to people, you start imitating them.
I'm not saying Vaggi is going to be close to Alastor as Niffty is btw. But, it would be cool if they bond. I know Lucifer is there as well, but he needs to be a better father for Charlie first.
Carmilla is already her mother figure, let Vaggi have a full family too.
