The bellboy is a young employee of the Hotel Royale whose love for the gangster's girl Rita gets him shot in the back by Mickey D.
The bellboy appears in The Royale. He is one of the characters of the pulp novel recreated on Theta VIII, working the lobby under the eye of the assistant manager.
His subplot is one of the threads the away team watch play out. He is in love with Rita, who belongs to the hoodlum Mickey D, and against the assistant manager's advice he gets hold of a gun and resolves to face his rival. Mickey D arrives, sneers at the challenge and shoots him in the back as he turns away.
The killing happens in front of Riker, Data and Worf, who can do nothing to change it. Reading the novel afterwards, they find the scene exactly as written, and learn that the only people who ever leave the hotel are the buyers at the end.
