Even towards the end of the episode, all she told Urvashi was "I don't like it when you support Niketan..."
On the other hand, Urvashi never passed any such comment directly towards anyone.. and what she may have said indirectly was only because she was too upset with Sapna..
I didn't like this behaviour of Aashka at all.. I have never seen Urvashi bitching about them.. I wouldn't be shocked if she starts bitching about Delu to others in the future..
