Norman left the planet and, posing as a Starfleet sciences division lieutenant, signed aboard the USS Enterprise. To keep his android nature from being discovered, he skipped two appointments Doctor Leonard McCoy made for his physical without giving a reason, something which McCoy found suspicious.
The plot ultimately failed. Captain Kirk and Spock correctly hypothesized that the android population was essentially a hive mind and that Norman was the central control locus. The androids were deactivated when Norman's processors were unable to deal with a flood of illogic presented to him by the Enterprise's crew, causing him to shut down.
