Stardate 3619.2: Kirk is determined to hunt down a vampiric entity he failed to destroy in his past.
While Kirk was a young lieutenant serving on the U.S.S. Farragut, half the crew, including Captain Garrovick, were killed by a cloudlike creature Kirk felt he could have destroyed — had he not hesitated before firing. Eleven years later, Ensign Garrovick, the son of the late captain, is stationed on the Enterprise. On the surface of Argus X, a landing party, including the ensign, encounters the same gaseous creature. Several are killed but the cloudlike entity escapes and this time Kirk blames Garrovick, who also waited before firing. The creature leaves Argus X and Kirk chases it through space — when it suddenly turns to fight. It enters the Enterprise and begins to emerge from the ventilation duct in Garrovick's quarters. Spock is with the ensign, and the Vulcan is the first person encountered by the creature. Tasting Spock's copper-based blood, it flees back toward its native planet, Tycho IV. Kirk and Garrovick prepare a trap, baited with a large jar of Human blood attached to a matter/antimatter bomb. The creature is destroyed, and both Kirk and young Garrovick, realizing phaser fire was inadequate to hurt the creature, are freed from their earlier guilt.
