Asimov decided that Jeppson was right, and when he included the story in Nightfall and Other Stories, he changed the ending so that Marten was left with a feeling of well-being. Asimov and Jeppson kept in touch, and fourteen years after having dinner together, they got married.

The name Levkovich (and its many variants) comes from the Polish name Lewek, a diminutive of Lew, meaning lion.
