That's a great analysis. There surely is a connection. I don't think any of the other actors have ever gotten so many scripts from Umera and then portrayed those characters close to perfection, so effortlessly. Sanam Baloch and Faisal Q are arguably the best performers when it comes to Umera's scripts. They've never ever disappointed me in any of the shows above.
I also like Mikaal in Umera's scripts - which include performances from Durre Shahwar, Shehr e Zaat and Subh Ka Sitara. Adeel Hussan did Daam and Subh Ka Sitara..and Daam is one of my most favorite shows. Needless to say Junaid was so well enacted by Adeel.
