	Synopsis: When the Enterprise enters the unchartered Mare Obscura ('dark sea') dark matter nebula, Data is in charge of scientific observations, together with young Dr. Lieutenant Jenna D'Sora, who shows a romantic interest in him. The human crew is clearly unable and/or reluctant to give Data reliable advice, and Troi warns him against trusting in literature on the subject, but since Riker says nothing beats true love Data decides to try 'running' a romantic program with her, yet method is madness in a human lover's eyes... Arrived at an M class planet's coordinates, the Enterprise finds it gone, inexplicably, while Worf fears disappearances and unexplained entries aboard constitute a major security risk. Indeed next strikes make victims among machines and crew, but according to Data all can result from proximity of so much dark matter causing gaps of space, which the ship phases' in and out of. The plan is to send an observational shuttle ahead, Picard decides to pilot it himself...
