it was Halloween and Charlie had the idea of inviting anyone who wants to go to the hotel but to enter to her Halloween party it's necessary a costume, duh. Angel dust as a nurse and Husk as a patient, charlie as Christine and Vaggie as the phantom of the opera, and Alastor... He showed up wearing a cowboy costume?! You were in the party wearing your costume but when he saw you he approached and greeted you

"Howdy partner, are you going down to wet your whistle at the saloon tonight?"
