I will just say that we only trust the one we want to trust; I believe that and from now on, their is no going back for any one of them - Sanskaar, Swara, Ragini and Lakshya.
Somewhere along the lines, the whole Maheshwari Family, Shekhar and Lakshya have seen Ragini in much good light as compared to Swara just because she has the ability to say the truth and they never actually cared to see Swara's viewpoint on things. This has continued for a really long time now. They are just blinded by Ragini's fake drama and they refuse to see the truth.
Whatever Sanskaar did and said today was the complete truth but still Lakshya refuse to believe the girl he believed to love and once again stood blinded by the false image of a friend. Even when his father wanted to question Ragini, he stood in front of her. Never he stood by Swara, because his love was never able to gain the trust.
