hey guys,
Now that Gauri has come to know abt Sam's BT, I think soon Sam will come to know that Gauri knows the TRUTH. He may then ask Gauri to remarry like Gauri did to Shiv when she thought she had BT......He may say I will go for OPERATION only if Prateek and Gauri marry etc etc EMOTIONAL BLACKMAIL.
Then may be He doesn't have BT, Prateek is Evil ( may be Mama, Maya or Ippi is also with him ) like Gauri realised during Shiv-Ippi wedding. And he runs to stop it. Weather he will stop (I guess he will ) or not.
Or may be after OPERATION his memory will go BACK and he thinks Gauri is Shivs WIDOW and he now wants to get her married to someone - Prateek thinking Prateek is her friend and will take care of her etc etc. Family can't tell him that he is now GAURI's HUSBAND.
