10. The Next Generation - Silicon Avatar

Dr. Kila Marr, a xenologist, is assigned to the Enterprise after another encounter with the Crystiline Entity. She has been studying the creature since its attack on Omicron Theta, the colony where Data was created and the attack wherein she lost her son to it. Through Data though, she manages to hear her son's voice again, as the colonists downloaded their logs to his brain before the attack. In what could have been a bittersweet episode, dealing with the strive to continue after the grief of losing a child, the story switches.

Dr. Marr wants revenge. The Entity, described like a whale devouring cuttlefish, is simple consuming what it needs to survive. But to Marr, this is a monster that destroyed only the life of her son but her family and her legacy. When given the chance, she initiates a pulse that finally shatters the creature like glass. While Picard is outraged, she feels a cool sense of satisfaction.

She has avenged her son and she turns to Data to get the confirmation that she has done well. Data does not deliver this. Her victory becomes hollow when Data, respository of her son's memories, informs her that her son would be ashamed of her actions. The Entity may have destroyed her son but vengeance has ruined her life.
