Having watched Hazbin Hotel multiple times, I have a few things to comment on.
Okay so, big Chaggie fan - massive. But at the same time, I feel like their relationship is really underdeveloped. The entire season, we see Charlie focusing on the Hotel, doing things for redeeming the sinners and only at the end we get a small intimate moment between them.
Vaggie to me, seems to be overlooked a little by Charlie, as she herself has stated that she doesn't see a point in herself unless she actively helps Charlie with whatever goals Charlie has. Her role in the series is that of a support and helper rather than a partner who supports Charlie WHILST also having her own goals.
Having said that, I hope that in the second season, we get to see Charlie prioritise Vaggie over her ideas and whatnot, with Vaggie developing a strong sense of self and self-worth now that she's fully revealed herself to everyone.
