Dr. Bashir is caught by Data using the Enterprise computer system to analyze medical equipment discovered in the Gamma quadrant. During their investigation, Data is struck by an energy beam from the equipment causing him to lose consciousness and experience a dormant program installed by his creator that was meant to be activated when Data achieved a certain level of development.
