my POV is that this time dutta behaved very differently and it was his heart that was hurt not his ego. he has been a very egoistic person like all men. the evidence is nakku's speech ,at the cliff hanging time. she had said that "yahan ke bhagwaan dutta sriram patil..woh jo karte hain wahi sahi hota hai...aap ne kaha mein gunehgaar hoon to hoon...aap samajhte hain aap apne desisions mein insaaf karte hain"....bla bla..so in a way nakku pointed out that he is egoistic, he is his marzi ka malik she clearly showed him the mirror and also reminded him that he is after all a human being who can make mistakes...(wow..nakku knows dutta more that dutta himself!!) and that time i would say that YES his ego was also hurt ....
but now i think its different..on thursday he never said that " nakku u refused DSP's proposal? how could u do this?"....what his words expressed was grief . he was just trying to find out the reason behind nakku's denial. he said that he never gave importance to her color or roop...he was extremely upset and was questioning nakku why she let him dream big?? why she let him have bharosa on ppl?? why she showed the ray of hope to dutta? the fire in him had died so why did she ignite it ahain??..........and after he has fallen for and is proposing her then why did she refuse his proposal?? is she scared or is she feeling that she is not worth dutta because she is dark? or is it that she has not forgiven him??....i think it was only hos broken heart nothing more than that....
previously when dutta came to know that sups betrayed him he reacted violently..that was not his true love so it was obvious that his ego was hurt. at that time he has said.."agar use koi aur pasan that to ye mujhe kehna tha...poocha tha main ne use...dhoka dene ki kya zaroorat thi??..main use nahin chodoonga"....and he went to take revenge , to punish her and that WAS ego!! but i never felt at any point that his ego was hurt on thursday...
what do u guys feel??? if it is his ego then he wouldnt to to save nakku also..just my POV
