IF ASR had seen Lavanya in place of Khushi, would he have married her also? Would he have carried on with the same set of actions?
In my opinion NO. He would have been more resourceful and found some other solution to save his Di's marriage without having to sacrifice his freedom and compromise his beliefs.
That makes me think that he did not marry Khushi solely to save his sister's marriage but also for the emotions he feels for her. Yes, a part of him married Khushi so to save his sister's marriage and keep Shyam tied to his sister, BUT a part of him also married Khushi, so she would be tied to him and not belong to anybody else. He probably would not be able to digest the fact of Khushi with another man...
Anybody else share my opinion...
