Lieutenant Jon Stephens was an alias taken by Lady Q when she visited the USS Enterprise-E in 2380 in order to be a direct participant in the battle against the super-sized Borg Cube. "Stephens" claimed to have been born on Mars and served as Conn officer on the Enterprise. Part of the fabricated history for Stephens included the "fact" that he transferred off the USS Excalibur-A for being too "strange" for Mackenzie Calhoun's crew. (TNG novel: Before Dishonor)
