Vox having his suicidal-homicide meltdown were all assuming this was the point Alastor goes "oh he's less predictable than I thought he's no longer safe to play with" BUT HEAR ME OUT
Vox hitting this point flips the script. He's on the edge, he's psycho, he's no longer playing it safe, or for kiddie games, he was willing to sacrifice everything for Alastor and a single end goal -
And Alastor isn't repelled by that - He's captivated by it - it triggers his own obsession with Vox, it uno-reverses the yearning.
He's no longer being non-chalant and acting indifferent or avoiding unless he's ragebaiting - he's walking the border of the Vees territory almost constantly. He finds every camera in Hell and makes sure they're on him at all times, he's no longer blurring himself for any of them including the drones. He kidnaps a drone and actually takes it back to the hotel. He's finding ways and excuses to get close to VeeTower. He saves Voxs body and memorizes every little component in it and how it works. He's going to overlord meetings insisting EVERY overlord must attend not just a "representative" so Vox has to look at him at least weekly.
Because now Vox isn't just some puppy-eyed plaything, now he's actually threatening, now he's actually interesting.
And Alastor loves interesting things.
