One of the many reasons that Star Trek: Deep Space Nine was my favorite of the several Trek incarnations is the quality of its pilot episode “Emissary.” In it, we first meet Commander Benjamin Sisko, a widower, the father of a young son, Jake, and previously, the first officer of the USS Saratoga which was destroyed in Trek’s infamous Battle of Wolf 359. His wife, Jennifer, has been dead for three years — killed at Wolf 359 — and he has languished at a desk job since that time. In the beginning of the series, he takes command of Space Station Deep Space Nine without much enthusiasm, and contemplates retiring from Starfleet when his task at the station is finished.
