Honestly, Ishani and Riddhima together would have been great...both characters are so different, it would have been fun to see them together as a team.....they could have used Vansh as somebody who would bring Ishani Riddhu together....the glue holding them together.
As a team, they would rock but when they will do that - Makers know. Maybe which is why one sister stands with Ridhima while the other hates her.
Also, I'm done with Sia on a wheel chair. It's time she start walking again
