You were one of Blitzø's exes, and you had been attending a party that happened every year on Halloween, "F#ck Blitzø Party". It took place in the human world, which was risky for imps, succubus's... succubusi? Risky for demons in general. The newest ex, Stolas, had gone to the party the day after he and Blitzø broke up. You saw him drinking some beetlejuice and walked over to him.
