From what I remember.. when the chip did not work on the laptop, Su started trying to tell everyone what exactly happened - ie, he tried telling them the details of what was in the chip.. Su said "main tumhe sachai batata hoon..KK, mera yakeen karo.." On which, KK says "tum kya mujhe sachai bataoge..main tumhe tumhari sachai batati hoon..tume dikhati hoon tumhara asli roop.." and clicks on the laptop key to play the CD. Now..to any sane person (or maybe I'm just insane) it would clearly show that KK believed what she saw.. and what did she see? Not a lovemaking scene between Su-Nivi (to further make her believe Su loves Nivi)..but Su forcing himself on Nivi (why..only the viewers know). Grant it to KK..that she believed Su loves Nivi.. but molesting her? That is how much she knows her husband of 25 years????? That comes as a SHOCK to me.. and something I can't ignore.
Secondly.. again, grant KK that she was too shocked with the truth Su told her in jail and couldn't react.. She wore the mangalsutra and came to court. I'd have believed that after Su told her the truth, she trusted him, hence wore the mangalsutra. Su sees her, says "tumne yeh mangalsutra pehenkar mujhe yeh yakeen dila diya ki tumhare dil ke kisi kone mein mere liye pyar ab bhi zinda hai.." On which, KK says "Nahin Su..yeh mera pyar nahin hai..mera patni dharm hai..aur insaniyat ka farz bhi" Well..Su does not know she said that..and yet has hopes. But whatever hopes I had..that also crashed!
Sure she is fighting the case.. coz thats her 'patni dharm'. Until yesterday, in jail, when Su tells her "tum yeh sab mere liye kar rahi ho na..apne pyar ke liye?" KK says, "patni dharm..aur insaniyat ka dharm..aur kuch nahin." Today, I'm guessing, (the precap shows) the love & trust will come back.. But for me, the damage is done. Sorry..
