Hi Sindhya,
Good observation! According to me, there could be two possibilities for the "spark" missing..
1. It was not meant to be intense & passionate....it was supposed to be an expression of relief, a reassurance of trust, faith & comfort in the arms of your partner.
2. Ever since the confession, as has been observed, the so called "steamy scenes", which was there in unnecessary excess prior to it & immediately after, have suddenly disappeared...this could be the result of many thoughts & views expressed in the Forum, disapproving the same between nineteen year old College students....& rightly so! & especially, when there was & is absolutely no story or seriousness in the MN plot, backing or justifying those scenes. I'm sure the CV's have read some of these opinions & it could be an attempt to balance those excesses with the current "passion-less & not so lovey dovey scenes"😆
An attempt to keep all sections of the viewers happy, perhaps! (They are failing miserably though, thanx to the current substandard MN & SG tracks!)
Sadly, what's happeneing is, Rati being the fantastic actor that she is, somehow managed to bring in a certain amount of genuineness & sweetness in the scene, where as AB who I feel really needs to work & WORK HARD on his expressions (he has his good moments too, as an actor, but is terribly inconsistent), could not do justice to the hug or the scene....in fact, throughout yesterday's episode, he had a blank look in his eyes & NO EXPRESSIONS!
'Bout personal differences, if any, between AB & RP, as suggested by some, I think they are professionals first & foremost & would not allow such differences to interfere with their job! I'm sure their careers as actors means a lot to them!
