Do you guys really think that Ishaan,s family really meant what they said about how come Suhana accepted a person like Ishaan??? did he need defending??? I dont think so, remeber after the resturant incident Rajni was maha upset and what did Inder said to her " I will not say anything to Ishaan as I dont want him hurt" , they tease each other really badly but they dont mean any of it, they were horrible to Elaish about his job, now that he got it , they dont tease him any more. Suhana didnt need to defend Ishaan as this was between brothers joking to him, imagine in real situation you jump to your brother in law about how dare he makes fun of your husband, what would be the answer from both, " Hamara aapas ka mazzaq hai , why are you so touchy about it".
As far as Suhana,s reason she should say " My Dad choose him for me" a most valid and solid reason and there is nothing wrong in accepting it. I think at some stage she would say this as per OBS.
Sonali is a TRUE friend indeed as she came ALL the way from US to SAVE Ishaan,s mairrage , which I think didnt need to be saved, Suhana would have taken more time but she would have figured it out herself that she loves Ishaan just as she accepted the family with open heart and changed her lifestyle , its not easy to leave a lavish lifestyle and adjust to middle class , she did it. Its a drama they could put any drama in it, but in reality character like Suhana would have taken time and SOME initiative from Ishaan as well to make her realize about the importance of Ishaan in her life. In arrange mairrages, trust and friendship comes first and then love!! belive me thats how it works!!!
