After they reassemble the newly found android, which also exactly resembles Data, they learn the android is named “Lore.” Lore tells the crew he is Data’s older more perfect brother.

Episode Notes
Log Entries:
*Captain's Log, Stardate 41242.4. Our last assignment has taken us into the remote Omicron Theta star system, home of our android crewmember Lt. Commander Data. Although we are due at our next assignment, I have decided to Data's home planet for a few hours in the hopes of unraveling some of the mystery of his beginnings.
*First Officer's Log, Stardate 4124.5. We have found Data's home to be a completely dead world down to lifeless vegetation. No insects-- not even soil bacteria. What is it that could kill everything on an entire planet?
*Captain's Log, Stardate 41242.45. Despite having only a few hours in which to explore Data's home planet we have discovered something which may explain Data's beginnings if we can properly assemble and communicate with what we've found.
*Captain's Log, Stardate 41242.5. Thanks to Lore's report, we now know what happened to the colonists. Beginning with a child's drawing, enhanced by Lore's description, our computer has constructed an image of a great crystalline entity which feeds on life, insatiably ravenous for the life force found in living forms, capable of stripping all life from an entire world.

Marina Sirtis (Deanna Troi) does not appear in this episode.
