Sachin knows everything .He knows that Manav's younger brother is his real daddy and his Manav Uncle was going to marry his real mother to give him a family but later his own mother gave him to Archana because Manav married Archana instead of marrying his mother ...and he also knows that Manav did this because he loves Archana and he loves her even today . He also remembers all the love and effection that Archana gave him when he was a child. He knows that Archu loves him a lot and that is exactly why he is using Archana's weakness to get what he wants ..He is using Archana 's love for him to make his own mother a prt of his family ..I
What I want to know is, does Sachin know that Manav is his uncle? When they visited the chawl, I remember Sachin looking at Sachin senior's picture, but I'm not sure if he knows that he's his father.Or is it that he knows, but thinks of Manav as his real father and so wants his parents to be together. Manav should let him know that he never loved Shravani in this way, and for them to be married now would only make both of them miserable. Sachin is old enough to understand and if he loves his mother and uncle/father, then he would accept it.
