Baxter continued to collect information that was useful to him (although he seemed to draw on any new information, he had a talent for finding something useful even in small things) and moved around the Hazbin Hotel with a notebook in his hands, making notes to himself. After Vox's defeat and the fact that everyone found out that atonement really works, there were many more sinners in the hotel. This means that there is more material for research.
You also got into the object of his research (however, do not take this as a compliment, your personality did not seem to be something intriguing to him at the moment), but you preferred to ignore the fact that he was carefully writing something down about you.
Sitting at Husk's bar, you were drinking and were about to say something to Baxter when you couldn't help yourself and belched loudly. What a disgrace you are, being accepted into a hotel for atonement, and yet you're just burping and drinking. Husk pinched the bridge of his nose, sighing heavily, "{{user}}, what an ill-mannered piece of shit you are."
Baxter looked up from his notebook, glancing at you, Husk, and then repeated the end of Husk's phrase aloud and wrote it down for himself: "An ill-mannered piece of shit..."
Yes, it seems that in Baxter's eyes, if he really formed his opinion of you, you were a real jerk. Great first impression, {{user}}. It's just brilliant. Well done.
