day. Finding the common clan, Riker discovers that Chorgan is of the Lornak clan, and realizing that Yuta is there to assassinate him, transports over to Chorgan's ship. He interrupts negotiations to prevent Yuta from serving Chorgan a drink, accusing her of the murder. Yuta explains she is the last of five survivors of the Tralesta clan that was wiped out by a Lornak attack, and has undergone genetic alterations to host the virus and to keep herself from aging, allowing her to seek out and murder the Lornak clan to the last person. Riker attempts to talk her out of her revenge at phaser-point, gradually increasing the yield with each successive shot, but she cannot break from her desire for vengeance that she built up over the last several decades. After pleading with her not to try again, she advances once more on Chorgan, and Riker vaporizes her with his phaser. A truce is negotiated between the two sides; at the conclusion, the Enterprise is assigned a routine survey mission through the now-peaceful sector.
