Mr. Dark, also known as the Illustrated Man, enters the library, looking for Will and Jim. When Mr. Halloway refuses to provide him with any information, the Illustrated Man threatens his life at the hands of the Dust Witch.
The Illustrated Man questions him about his age and entices him with the promise that he can be young again if he really desires it. Halloway's vehement "No!" only further exposes his innermost wish to shave off some years from his age. The Illustrated Man has recognized Halloway's dissatisfaction with himself. He now leaves Halloway while he himself prowls the library's corridors in search of Will and Jim.
