I think today Arti and Yash have bonded for ever .now No matter what, they will stand up for each other in times of need and think and do which is good for the other,even if they will have to go through lot of pain on their own.
No amount of hatred and bitching from the family will do them apart.
Awsome episode.the silent understanding and realization arti experienced today and the sense of duty and the peace yash got form doing all this was a tribute to each other .These feelings are bigger than the love itself.Eventually LOVE will follow...i think it has already sneaked into their hearts ...
