Some of you asked about her, well you get you wish. Kai will return in next week's episode An American Benwolf In London.
She finally appears right when Julie no longer a regular, no longer Ben's girlfriend, I always wanted to be Kai and Julie interact, and be each other's rivals, maybe become friends later on but in the beginning Kai is someone that gets on Julie's nerves, Kai would have been a much better nemesis for Julie than that pshyco Elena. At least Kai is on our side, have them been rivals who are both good guys and not one of them be a villain that kind of ruins it.
