Focus of Channel 29 should've been on Dr. Sinha and Neha, but entry of Kabir's past and Tarini into the equation shifts the focus from Neha's accusations, to Kabir official and unofficial pasts (Divorce and Tarini). Looks like all the pasts seem to intervine one other at some point:
Kabir's past - Malvika knows KB's past or a part of it definitely. KB knows Malvika knows and he doesn't show surprise.
Dr. Sinha's past - KB knows something about Dr. Sinha's past, that proves the present accusations false.
Ananya's past - The girl can see KB reliving the ordeal she and her family went thru years ago. She can relate to his present, but alas there is no one to relate to her past.
KKN's past - Saas is worried, KB's past may take KKN back to the pre #2 past position. Saas has his priorities set right.
Khalid, Malvika, Neela - are unable to make KB ask for forgiveness. Ananya is unable to make Kabir present his side of the story. Loved it that KB doesn't Apologise nor does he justify himself.
Officially, KB concentrates on digging out more info on the hospital where Sinha worked. Unofficially, he tries to find out who dragged Tarini into all this mess.
Officially or unofficially, its not about him.
