Log Entries:
*Captain's Log, Stardate 44932.3. The Enterprise is preparing to enter the Mar Oscura, an unexplored dark matter nebula. Commander Data is modifying several of our photon torpedoes for an experiment designed to elicit more information about this unusual phenomenon.
*Second Officer's Personal Log, Stardate 44935.6. After conferring with my colleagues on romantic love in general, and my own situation in particular, I have reached a decision.
*Captain's Log, supplemental. This series of unexplained events has now resulted in the death of a crewman, but it appears that Mr. Data may have an explanation.

With the exception of his narration of "Data's Day" via his personal log, this is the only episode of the series in which Data is heard to record a personal log entry.
