how was reena kapoor's entry doe in the show?

I missed a couple of episodes of WRWMK so i was wondering how was reena kapoor's entry done?? it is weird how she is just there because it s liike 3 generations of look alikes and she is also pari's adopted daughter so its weird...they should have just done like differen't set of stories of WRWMK instead of doing a continuation beucase it makes the totality of the story line really weird...
