friends, i think Antara is still negative. if we recall the 29th november episode of kumkum, we hear the mysterious man talking to the maid Meenu. he says that you know antara very well and you have to do whatever is ordered otherwise your kid....
this indicates that antara was doing all this drama to stop dhruv/siya wedding and to enter wadhwa house again. as we see Meenu was impressed with the family's generosity, she wanted to tell the truth to kumkum, and may be thats why antara planned to kill meenu. 😡
