This character Drexler was named for production staff associate Doug Drexler. This name did not originate in the dialog or script of a canon production, but was featured on set artwork including the personnel file of Lieutenant Keith Rocha. Coincidentally, Drexler also played an unnamed Starfleet crewperson of the same era, as an extra in a cameo role that might be the person referred to here. There has been no cause given to corroborate the unnamed character played by him with this unseen character named for him.
