my unsolicited 2 cents on the bi-han/sektor situation.
i think they were better off as comrades. if nrs wants to explore romance territory and dabble into relationship dynamics so badly, then sareena was the best fit for that since she and bi-han already have history together. it only makes logical sense to build on it. genderswapping a character for the purpose of shoehorning romance does not. anyways, i don't feel particularly strongly about this development, i'm more "eh" about the whole thing. furthermore, it's officially canon bi-han likes strong, intelligent women and i love how both sektor and sareena embody these traits in different ways—sektor for her technical prowess, and powered by her armour; sareena for her practical smarts and supernatural abilities. at least his tastes are consistent enough to offset any feelings of disappointment.
