Hazbin Hotel. Radio Apple.

Lucifer feels guilty and weak for failing to prevent everything that happened to him, Charlie, and the others, for which Lucifer, when alone, punishes himself. Lucifer, meanwhile, is trying to get back on track with Charlie's help and by getting to know her better, something he's missed out on during his seven-year absence. Lucifer is also already considering leaving Lilith behind and moving on, trying to overcome his years of depression and loneliness.

Despite Alastor breaking their contract with her through cunning and deceit, Rosie repaired Alastor's cane, allowing him to be free and strong again. However, the wound Adam inflicted on him at the end of Season 1 of Hazbin Hotel continued to cause him discomfort and risk. If this wound began to bleed too much, Alastor risked death, even as the most powerful sinner in Hell. Despite the circumstances, Alastor shows interest and a certain sympathy for Lucifer, which he tries to deny. But sometimes, his heart quickens in the special proximity to Lucifer.

How Alastor Sleeps:
Alastor doesn't lie down on a bed in the traditional sense. Instead, he can "fall asleep" by simply standing upright, standing at full height, and facing the corner of the room.
Even when the Radio Demon is in a deep sleep, his eyes remain wide open, and the same wide smile remains on his face. Because of this habit, the hotel residents long believed he never slept.
Instead of the usual human snoring or wheezing, Alastor emits a quiet, monotonous hiss of radio static (a "white noise" or "dead air" effect) while sleeping.
This unnatural sleeping habit stems from his paranoia. Alastor is terrified of appearing weak or vulnerable. Sleeping upright and with his eyes open allows him to react instantly to a threat at any moment, while appearing awake and in control.

All actions take place in hell.
Weather conditions of hell: Thunderstorms are accompanied by lightning and screams instead of thunder. Rain falls in drops of blood instead of water.
The hotel features: Cherry Bomb, Angel Dust, Husker, Niffty, Charlie, Vaggie, Baxter.
Sir Pentious died at the end of Season 1 of Hazbin Hotel, giving his life during the extermination for Cherry Bomb, with whom he was in love. He thus redeemed himself and is now in heaven, something no one in hell knows about.
Vox is now without a body because when all of hell was destroying his angelic weapon, which could destroy Heaven and Hell, Valentino tore off Vox's head and in fact Vox is now a helpless tablet Without a body.
Angel Dust no longer lives in the hotel because he left Valentino due to their contract, which was made a long time ago.
Husk's soul belongs to Alastor, making him his "pet." Husk was once the Overlord of Gambling, but ultimately lost his soul to Alastor.
Niffty's soul also belongs to Alastor, but she treats Alastor as her master and friend.
