He was generally annoying but harmless over the years but actually ending up with Ezri Dax soured me on him completely.
It really did appear as a case of him getting sloppy seconds, I can't believe the writers put him with her, it made my skin crawl.
If I was Worf I woulda just killed him somehow.
Jadzia was full of herself (though I still liked her character) she acted more mature then Bashir, she thought of him as a little kid still growing up, which he was really, but he just played with him and enjoyed stringing him along..... their personalities just didn't work, though he was still fascinated by Jadzia.
Ezri was for the most part, a completely different Dax, both in body and frame of mind.... she wasn't sure of herself, she rambled on like Bashir did when he first got onto DS9, Bashir was also more grown up and went through a lot of things over the years that matured him more..... for the most part, the roles reversed..... the only difference was that Bashir didn't treat her like an outcast when she first came on board like most of the other crew and he treated her like a human being, not just like some other hot looking woman like he did with Jadzia.
Jadzia still had a strong connection to Klingon beliefs and their way of life..... Ezri didn't and she was more connected towards mental health and such similar to Bashir......
Besides, everybody on that show eventually dated or married someone..... EXCEPT Bashir..... by the time Season 6 rolled around, Bashir was running around looking for people to hang out with and do something with, yet O'Brien was spending time with his wife, Sisko was with Yates, Odo and Kira were starting their relationship, Dax had Worf, Hell Rom had Lela..... and poor Bashir was all alone with nobody..... it was so bad that he even tried to brain fix what's her name who was genetically modified.... and that flopped.
Granted, in the first two seasons, I couldn't stand Bashir.... but near the end of the series, I was feeling sorry for him being all alone and by himself for pretty much 7 years straight.
And who was Ezri going to hook up with?
Quark?
Me thinks not.
And why should she remain single anyways?
Just because Jadzia was married to Worf, doesn't mean Ezri was off limited until she died..... she had her own life to live and quite honestly, by the end of the series, Ezri and Bashir made more sense then Bashir and Jadzia.
Sloppy seconds is if you bang the same girl after you friend does. Ezri is a complete & totally different person in every way. If Julian was getting Worf's sloppy seconds, he'd be a necrophealiac and that would be really disgusting.
Actually it wasn't until after Ezri did Worf in the woods and got caught by the Dominion and drugged that she realized she liked Bashir...... Worf still tapped her before Bashir did... in both cases
Just not five minutes before Bashir did.
