I really do not know but I did not liked this episode. I somehow felt little stupit and to be honest, we get the real nature of Saffron in her previews appearance - so somehow it felt like something old is just brought in, made another steal something episode without no real value..
But other than this.. it was adventure episode and the stealing job looked like going wrong all the time.. and when Saffron left Mal into the dessert.. I really wondered - are they going to end it like that but then Inara showed up.. I think it was a clever twist.. I did not expected it.
