I seem to have lost my earlier response. Here is what I remember
Like the weatherman said - there is a 50-50 chance that it will rain, there is a 50-50 chance that Karan will turn negative. But it may be for a short time probably to ferret some information out (probably out of Abha).
It made me also think - who in the household has not turned negative as yet - Karan, Abha (least likely to turn -ve at this stage), Ranchod, Veer bhaiyya, Swarna Prakash, CP, Raghav Mama and Pratibha). Is it going to be like the Usual suspects - suspect the least likely person ???
BTW the glasses really make him look more mature and the whole package matches and complements Abha's mature look. Those glasses also give him a sinister look (or may be it is KG's acting). 😕
Coming to the shirt incident - Intimate would be if Abha was caught sewing the button while Ranchod had the shirt on. Remember Kasam Se - Bani stitching the button on Jay's shirt with the song "tujhe dekh -2 sona", that is intimate (kind of). A more acceptable or credible Karan dialogue could have been - "Itne saare naukar hai ghar mein, aur tu meri biwi ko de raha button lagane ko...and so on". Anyway point taken Karan loud and clear, you are possessive about your wife (evident right in June 2010 episode - Sanskar leaving for Delhi - to court Sanya. S, S, K & A having dinner in Delhi - photo incident).
Creatives haven't you all hear of the KISS method - Keep It Simple Sweetheart - why did you get A & R married ? Why ruin your son - R's life even before it has begun. When the lady protested so much and laid down so many conditions, Jaggu could have sent his DIL study law since he knew at the very outset that she had wanted to become a lawyer. It was very evident that he was taken in by her, when he asked her to assist one of his lawyers - Ricky Sir. (yeh bhi mujhe hi batana hoga ... dah)
Last but not the least - When did Veer get married and who told that to Karan ??? Hole in the plot or was that a blooper ???
