Just like we have the dessert at the end of the meal, because its the most scrumptious part of the meal, there is a saying "you save the best till last" (that can imply in any case or scenario)..so I really don't see it as a big deal that Suhana would introduce Ishaan last. At the end of the day the media came to see Suhana and the whole family, so all were there and she was introducing them, as they came. Anyone in her position would become bemused and bewildered because she was not notified, so there was no preparations. She was fumbling a little to begin with as she was taken aback, which is perfectly natural..it was a matter of trying to deal with the media and the family at the same time. Basically she was put in the deep end, thankyou our dearest Ilesh miah!
Now I am sure if Suhana and the family were aware, then there would have been plans/rehearsals of who will go when and who will say what. It was completely on the spot, spontaneous, no time to think or prioritise! The circumstance was ugly again because of Ilesh's careless deeds!
