If Dadi Garima Come to GH then they past may unfold and that might cause trouble in the marriage. rather than Shyam or Dadi.
If Dadi didn't go to GH the the Roka will happen without hindrance.
But still I wonder how the things for the marriage will move without the meeting of Garima and dadi Lets see how the CV's are playing the cards.
Its not Just 2 Villans ( Shyam and Dadi) now 3 villans (their past and indirectly Garima) If Garima and dadi get to meet each other that will create the turmoil.
I mentioned in one of previous Post that definitely Garima would recognizance dadi.
