Episode cast overview:
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

Data Dances....and Smiles!
24 August 2014 | by (United States) – See all my reviews

This episode reminded me of those MASH episodes where one of the characters would write to a relative about what was going on daily in their lives. In this one, Data writes to the Daystrom Institute to tell of his efforts to assimilate himself into the crew by exploring and donning human traits. He has bee chosen to be the best man at Chief Obrien and Keiko's wedding and he experiments with all the intricacies of that process, including the seeming cold feet of the bride. In one of the funniest moments of the series, Beverly Crusher is enlisted to teach him to dance. She doesn't know it's for a wedding and teaches him to tap dance. He is very adept because he need only follow her moves When she realizes he misunderstanding, she tries basic ballroom technique with varied success. He does get it, but is stiff and awkward. She tells him to smile and he gets this plastered-on, ridiculous grin as he dances, first with her and then with a holographic partner.

There is also a serious event going on. A Vulcan ambassador is on board the Enterprise, ready to beam over to a Romulan ship to begin negotiations, representative of the Federation. She is killed as she transports over and the Romulans accuse Picard of underhandedness. It is well worth watching to see how this all plays out.
