Sherlyn as a vamp isnt easy to be liked but the actor is pretty. I started the show much later and didnt like her initially but with the passing of time , she has grown on me too..Rishabh and sherly are often seen sitting together in awards prog. and they do look good together. She is here to stay , if she isnt seen like in a week ..her absence is felt.
About her pregnancy , don't think the actual dad thing will come out so easily. Even if Sherlyn seeks revenge from Luthras and plans to go back to punnu with her tummy baby, she just can"t afford to lose the title of Ms. Mahesh luthra. If her truth is out , she will ask for forgiveness ( before mahesh luthra comes out of coma ) and she will be forgiven as she is kareena's favorite .
Cvs have forgotten about Pawan after mahira's new mom 's entry..i am more into his Srishti pataoing.
Omg..my reply got longer than your post.
