After breaking up with Lyder, and having a fling with a Sabbac dealer on Zeltros that caused a bit of a stir among some of the crew, Narruna decided that in order to get the crew to not think of her as a woman of easy virtue (and to punish Jo'luk for some reason) Narruna decided to stop dressing so provocatively, and began wearing baggy clothes that completely hid her femininity and allure.
Jo tried to counsel her against this new fashion choice, trying again and again to get her to go back to her old, more revealing style of dress, but she seemed to be doing it just to spite Jo. Naturally, Jo could see no reason for it, nor remember what he could possibly have said or done to drive her to madness.
Apparently, it stemmed from a conversation she and Jo had, when she asked him if he thought what she had done on Zeltros was wrong. Jo replied that if he had had a relationship like hers and Lyders, he wouldn't have done what she had done as soon as she did it. Shocked and disbelieving, she brought up a number of Jo's past relationships, and how quickly he went from one to another. Confused, Jo informed her that he didn't even remember half the relationships she was talking about (he drinks perhaps more than he should), but that as far as he could remember, he never had a relationship as serious as the two of them had, but if he did, which he hoped would never happen to him, he would go on a depressed drinking binge for perhaps months (as opposed to his joyous drinking binges, which dominate the majority of his life) and wouldn't so quickly fall into the arms of a nobody on a tourist planet after a break-up. Plus, he felt Narruna could have done a lot better, and going from a Jedi to a Sabbac dealer was a sad, sad fall for someone as hot as her.
Being a woman, she didn't understand, and was mad at Jo for some time. Another reason why Jo preferred taking to bottles over talking to women. In his opinion, they were both filled with sweet love, and both fun to have late at night, but if you weren't careful, they'd both give you a massive headache come morning. At least you could cork a bottle. And, once they're empty, the best thing to do with them is toss them out the airlock. That last one was a joke. Probably.
Here we see Narruna, in her Hoth-wear, as Jo'luk cries out in agony upon seeing it.
