yash needs to see the beautiful bond that has developed between payal and arti, who is now her mummy, then he will realise what happened and why... right now he is moving like a man possessed . imagine he didn't even take a shower or change his clothes he just went to bed...really yash you need to get out of your trance...and arpita where ever your spirit is you need to go peacefully to the eternal life and then yash will probably get out of his misery...oh before you go... like a good mother disclipline palak so she can be a little six year old and enjoy life and stop being bua jr...
