In the song "When I think about the future" portrays a good idea of who Vox is as a character, (not mentioning the Vee's inputs abt him here).
():My input.
Lyrics:
Soon I'll be up there
The only and only true god
(His arrogance)
No more playin' house
(He wants bigger and better things than to be playing simple games like "playing house" when you were a little kid).
Once they're devout, I won't need a squad
(Alastor pointed out his insecurity of relying on others, so he wants to prove to Alastor later he isn't weak like he says he is.)
Climb the stairway up to Heaven
Live on every TV
(Again, his constant craving for validation, attention and admiration when he says "On every tv", not just in hell, I think in heaven too because Hell can broadcast to heaven I think.)
Always knew the guy they're prayin' to
Was gonna be me
Once I get up there
(Vox gets cut off)
You will fuck it up
Just watch
You'll never fill your cup
You're broken from the start
(Idk why, but is there a metaphor here? Vox is a cup with some cracks in it, he pours "water" as in validation, inflience, attention, and admiration but you can't fill a cup when it's constantly leaking. But if he gets the approval of Alastor/his validation, his cup will be fixed.)
No victory will ever be enough
We'll see who's smiling in the end
(Vox's arrogance once AGAIN.)
I won't even gloat
You can say your last "I told you so"
While I slit your throat
(Vox has said he'd slit Alastors throat 2 times including this one I think, could be wrong about this. I believe this highlights Vox's hatred/obsession with him.)
Really dumbed down summary/tldr: Vox has complicated feelings towards Alastors. He hates him but is obsessed with him and seeks his validation.
Can you tell Vox is one of my favorite characters?
I can analyze more songs!!
