Star Trek: 10 Things You Didn’t Know About Dax
4. Emony And McCoy
When the Defiant crew traveled to the Original Series time period in Trials and Tribble-ations, none were as excited as Dax, who had personal experience living in the mid-23rd century from her time as Emony Dax (the third host of the symbiont).
Dax was very nostalgic for this era, from the clothes to the tricorder designs. At the time, Emony Dax was a professional gymnast. In the 2240s, she judged a gymnastics competition on Earth at the University of Mississippi, and it was here that she happened to meet a young Leonard McCoy, who was attending the University at the time.
Apparently, the two got up to a bit more than gymnastics, as Jadzia remarked that she always had a feeling he'd become a doctor because 'he had the hands of a surgeon.' It was a hilarious moment and connected DS9 to The Original Series wonderfully, just like the rest of this episode.
