I was thinking about how vivzie said that vox would be an important character (especially on season 5) and that he would be relevant in next seasons. So here's my predict

1. I believe that we'll see him on his loser arc on season 3 cause yk he fucked up his reputation so I think he's gonna be part of the main cast as a guest from the hotel (this at final of the season after they defeat Alastor or humble him or something). Viv confirmed indirectly Alastor as the antagonist of the next season. 

2. On season 4 we'll see vox attempting to get redeem and failing cause he's too selfish to truly get it. We all now lute's gonna be the antagonist of the 4th season so I believe vox's gonna sacrifice himself in a selfless act to protect the vees (or Charlie idk) from lute, getting redeemed yay :D

3. And finally, he's gonna fuck it up, even if vox get redeem he has that hint of pure evil. A sudden selfless act doesn't mean he is completely good. Roo is gonna enter to heaven using vox, since she is the root of evil and more a concept than a real character (for now) I believe she've been watching, trying to get her opportunity to corrupt heaven. During pilot era viv said that Hazbin hotel wasn't going to have a good ending, so my theory is that everyone who's gonna get redeem during next seasons before 5th are also going to fall or worse in an attempt from heaven to keep Roo away


Hope this has sense, idk how to write, sorry guys 💔💔💔

I have a theory
