True. Sister ka itna sa bhi ounce was never present between.
LOL Imlie is still operating under the presumption of sisterhood, that's why.....she has forgotten her own nightmare where she had told Adi that this behen wala rishta will always be a bandhan - a tying down rather than an actual sisterly relationship.
Imlie may be trying to handle it maturely by not dragging Adi in between them but the harsh truth is that Adi will always be between them.....cuz they were never sisters to begin with......it was all an act from Didi's side and she really doesn't want anything in life other than Adi.....so she will always bring Adi in the middle of every issue whether or not he has a role to play.
