I'm very protective of aro Alastor so I don't actually want anything explicitly romantic from Alastor in canon (from HIS end, that is). That's what fic is for! Tho even in fics, I like to keep him aro-spec - which does NOT mean he can't be incredibly fond of Vox and have intense soft feels for him. I like mutual radiostatic where the type of love they have for the other isn't the same, but it's mutually intense, and works for them both, you know? <33 (That said, I enjoy demiro fics as well; Al with a crush is adorableeeee) But yeah, no, I personally don't want that to be canon.

But like I said, I do want them to reconcile their friendship, and then in fics we could use that as a jumping point for future radiostatic. I think Vox's romantic feelings for Alastor are pretty explicit canon by now: it wasn't said in as many terms, no, but all the little gestures, the expressions, the blushing - it's very clear that Vox was in love with Alastor, and likely still has semi-buried feelings under all the hurt and anger.

I also do think that he and Val have a good thing going, and I wouldn't want radiostatic to jeopardize that. (The Vees as a package deal! Do Not Separate!!) I'm firmly team "staticmoth can only ENHANCE radiostatic, actually". Val and Vox are both poly, and Alastor doesn't care, so I don't think there would be issues with them maintaining a polycule. And I think Vox dating Val too HELPS the radiostatic situationship remain at a healthier level, because that way Vox has Val to go to for all the affection and romance and sex he needs. Even if Al adores him and they have sex sometimes, it's very clear that Vox's sexual and emotional needs surprass that of Alastor's.
So if we have staticmoth as well, Alastor isn't solely responsible for satisfying Vox's sexual and emotional needs - which is less pressure on him, and less chances of resentment/greediness from Vox. My ideal scenario is when Vox and Alastor are primarily friends, Vox openly in love with Alastor and Al comfortable with that; Al also very fond of Vox; and them engaging in kinky sex sometimes, for intimacy, kink and power play. (You can take extreme kinkster ace Alastor from my cold dead hands.)

This is pretty much all fanon though XD Looking at it from a strictly canon view: I don't think we'll ever get mutually romantic radiostatic (which, like I said, I'm HOPING for bc it's nice to have aro representation) but I have seen nothing so far that would make a platonic reconciliation impossible. We're not even halfway trough the series, Vox is likely going to be at his worst now - and I think messing up with the rest of the Vees too -, but that still gives us two more season for him to claw his way back up and fix the relationships he cares about: the Vees AND Alastor, hopefully.
