It seems like there are 2 clips. In one, Rakhi is near the table where Rubina says the will you tell the daughter. In another, Rakhi is in the kitchen trying to hold Nikki where Rubina says tell your daughter. Guess the episode will make things clear.
Edit: So, in one clip Rubina is wearing a hair band and in the other she isn't. Tge clips are different. Seems like the fight was extended and this matter goes on for a long time.
