Sierra Pecheur ...


Second officer Lt. Commander Data accepted to speak a complete record of a day in his functioning for the benefit of scientific android engineer Commander Maddox and concludes his programming must be improved concerning interaction with human emotions, most puzzling given human practices such as irony. Chief Miles O'Brien's human wedding is amply confusing, even for Worf, bride Keiko Ishikawa's gibbers even more illogical. Learning dances and which is appropriate from Dr. Crusher prove easy. Conan Doyle's logic of elimination Data soon masters, in time to solve a mysterious accident during negotiations with a Romulan admiral... Written by KGF Vissers

The first episode to feature Data's cat, Spot, although (s)he is not named until later. Also, (s)he is a brown, long haired cat, whereas in all subsequent episodes, Spot becomes an orange tabby. This running gag of Data's character was trying for Brent Spiner, who claims to hate cats. See more »


When Lt. Commander Data enters his quarters, he walks up to the replicator and orders "feline supplement number 74" and a small, clear glass bowl materializes containing a portion of cat food. The quantity in the bowl greatly increases from the time it materializes to the time when Data sets it on the floor. See more »

Way to go Sherlock!
18 November 2014 | by (Bradenton, Florida) – See all my reviews

This episode consists of Data making a personal log in order to send to Dr. Maddox--the android scientist who would like to one day make his own version of Data. In it, Data talks about two main topics--- the upcoming wedding of Keiko and Mile O'Brien as well as the odd occurrences surrounding the Vulcan ambassador's time on the Enterprise. As for Keiko and Miles, Data is completely clueless that Keiko's hesitance to marry is based on a case of nerves and he feels that he must fix this 'problem'. And, the mystery concerning the Vulcan ambassador's death--which, to me, was a VERY simple mystery to solve and which I figured out INSTANTLY. The crew, inexplicably, was clueless and Data only figured it out when he began thinking like Sherlock Holmes. Way to go, Sherlock!

So is this worth seeing? Yes. However, the second plot involving the Romulans and Vulcan ambassador was very weak. As for the rest, it's mildly diverting and nothing more--enjoyable but not exactly memorable.
