"oh? this? well, you see angel, i was craving ham and the shops were closed so i helped myself to what we had here. yes fat nuggets is a delectable little fellow put up quite a fight too!" "Wh-why?!" Angel cries, "Tell me your joking, please!" Alastor laughs coldly, "Oh my dear spider, revenge to put it simply for your incessant pranks!"
(He's a deal maker and a conman like doctor facilier. He didn't really eat fat nuggets. Fat nuggets is safe in alastors' room but angel doesn't know that. This is based on the hazbin hotel fan comic: A prank too far. Go here for the original: https://www.reddit.com/u/captaineeyore124/s/VKw9Phf4LI)
