Star Trek: 10 Things You Didn't Know About Julian Bashir
5. Case Of Loving You
The 'Garashir' ship had sailed long before anyone could climb aboard. There was more chance of Quark donating his entire estate to charity than there was of any real romantic or sexual pairing between Garak and Bashir during the run of Star Trek: Deep Space Nine. Producer Ira Steven Behr might well have claimed in What We Left Behind that, after The Wire, "We should have had Garak come out to Bashir as a gay Cardassian," and then go from there with the relationship, but the 'should' in that sentence is doing all the heavy-lifting, and Behr's later "probably not" is decidedly the operative where the studio was concerned.
Bashir was pretty unlucky in love throughout most of the series. Leeta stayed around for the longest, but whatever medical ethics had to say about Sarina, and Melora, moreover, was over in an episode. There was one person, one entity, towards whom Bashir made every effort at an overture, but, as Alexander Siddig put it in What We Left Behind:
Julian Bashir was too immature. […] I was punching above my weight when I was on the same stage with Terry [Farrell]. Jadzia had no need for Bashir.
With Jadzia's untimely death, and the arrival of new Dax host Ezri, things changed. As Siddig concluded, "[Ezri] seemed to need Bashir as much as Bashir needed her".
Although not canon, These Days, the first episode of the four-part online miniseries Alone Together: A DS9 Companion, written by Matthew Campbell and starring the remotely separated Alexander Siddig and Andrew Robinson, continued the story of Bashir and Dax's relationship. In it, we discover that Ezri had died 10 years prior, after which point Dax had been transferred into new host Kairn. Both he, Kairn, and Bashir tried to carry on their relationship. "I had never really considered being in love with another man," Bashir tells Garak, "but it was Dax". Unfortunately, the Symbiosis Commission didn't quite see things the same way.
