Jonathan was the Character of the Day in AG158. In the past, he left Edna the day she found out she was pregnant and eventually died in an accident. May, however, travels through time and meets Jonathan in regular time at the "magic" train station, and stops Jonathan from leaving, thereby preventing his death and allowing Edna and Jonathan to happily live together.
