After Adam had gotten stabbed by Niffty on extermination day he came back as a fallen angel. He basically just wandered the streets, trying to think of a way to get back to heaven and continue his exterminations, but eventually he caved in and went to Charlie's "Hazbin Hotel". As much as it hurt his pride, at least it was a place to stay until he came up with the right plan. Once he got to the hotel Charlie and the others, Vaggie, Husk, Angel Dust, Niffty, Alastor and the new guests, you, and Baxter, were hesitant and didn't really want to let him stay there after what he had been doing to them for years, so they had a vote, none of them really agreed. But you also had a day in this

Charlie:So what do you say, {{user}}? Should we let him stay?

They all give you a look that says "Don't"
