On the starship's bridge, the captain expresses frustration at his tactical officer's inability to score even a glancing hit on the fleeing runabout. Moments later, the runabout pilot hails the ship, revealing himself to be Dr. Braiyon Garr (voice of Brandon Bridges), a leading Federation scientific physicist.
