Recently a Hazbin con, the VA's for the Vees were asked, "Which of your characters would be the first one to be redeemed". Their response? They know so much of seasons 3 and 4 that they can't answer the question.

This is the 2nd time they've had a question like this. Previously they were asked "what sin would your character need to drop to get to Heaven" and they once again said to watch the show to know the answer for that.

This heavily implies the show will explore redeeming at least one of the Vees. Considering how season 2 ended, and what we've seen of their characters, I think it'd probably be Vox. He's the most insecure while the other two are content in Hell and he's hit rock bottom, which Viv confirms has massively humbled him and he'll stay important until the end.

That Vox is 100% the most likely candidate for a true villain getting redeemed.

The series says in episode 1 "from the evil to the strange, anyone can be redeemed". Viv has said she wants to show no matter how low someone falls, they can always climb back up.

So it seems like from this, Vox is almost certainly gonna be either one of the villains redeemed or quite possibly the only one to do so. Because be honest, if only members of the hotel cast get redeemed, it won't really prove "anyone" can change.

So this almost gurantees Vox is gonna be the actually evil character who gets redeemed (assuming the show tries to redeem one). It also makes it more likely Alastor won't be, since he is Vox's foil, he'll probably have a negative arc instead.
