Rubina I believe was more headstrong than Priyanka. She never really took WKW bashing seriously. I mean of course she felt bad about it but there was no change in her behavior.
Priyanka on the other hand has stopped fighting or speaking up in most of the issues which is good to an extent as she was going a little overboard but it is also effecting her mental health. She clearly seems disturbed even when shes trying to have fun. I hope she patches up with Ankit soon because they will now have a better perspective on how to take things forward.
