There he discovers a typewriter and a large stack of papers, which he begins to read when gasoline pours in under the door and lights.

Roger fights back, burning away the bandages to reveal another Big O unharmed. The robot then vanishes, leaving only a bandage to fall from the sky. Back at his house, Angel calls Roger to give him Schwartzvald's whereabouts. Roger follows the directions to find that Schwartzvald is throwing a masquerade party. Roger talks to Schwartzvald, who is dressed as a clown, and who uses the partygoers as an example of the corruption of the city. When Roger hands over the check, Schwartzvald burns it and the masks of the partygoers burst into flame. Schwartzvald cal

When Dorothy asks Roger if he would be giving gifts to anyone, he becomes nervous and declares that he doesn't like the gift-giving. This causes Dorothy to storm out of the room. The saxophone player, Oliver, brings home some ham with the money Roger gave him and tells his blind girlfriend Laura that he would like to give her a good Heaven's Day gift. Roger consults Norman on Dorothy's reactions and Norman tells him that Dorothy's birthday is apparently on Heaven's Day. Roger asks about Dorothy's dress size and then rushes off to buy her a nice coat, which Oliver is also admiring but can't possibly afford. Oliver gets his pay from
