A Lucky Shot (The Search for Spock)

Saavik and Dr. David Marcus locate a young Vulcan boy and conclude that it is Spock, somehow regenerated by the same process that created the Genesis planet. Captain J.T. Esteban is reluctant to permit Spock to be beamed aboard the Grissom immediately, and would prefer to contact Starfleet Command to receive instructions. This turns out to be fortuitous; shortly afterward, Kruge's Klingon Bird-of-Prey arrives. USS Grissom is unintentionally destroyed by a "lucky shot" from the ship's gunner. Kruge is furious, as he had desired to take the science ship, and its data, intact, and the crew as prisoners. Kruge summarily executes the gunner, vaporizing him with his disruptor. Torg points out to Kruge that there are life signs on the planet and surmises that it is a landing party, which pleases Kruge.
