The 'innocent flirting' while about to get married thing-- I think it's a 50/50 risk on that. Some people get extremely offended by it, others think it's harmless.
It looked like Worf ironically, brushed it all off.
In "Let He Who is Without Sin" she was doing some things with another female that looked very suggestive
. It seems like that's just the way the woman was.
Say what you want about Jadzia, she wasn't a boring.
However.....the ass kicking, hang around with Klingons thing-- I think they went too far with all of that.
Jadzia was also one of the sexiest characters on the show when she wanted to be. In "Through the Looking Glass" was a pretty good example.
