Guys...ek baat socho...
Chalo maan lete hain...Siya is the culprit.
But then why? What is her motive?
She is Vansh's biological sister. Vansh dotes on her. Toh kyun woh Vansh ke khilaf saazish karegi?
Unless...Siya and Kabir were in love n Vansh didnt allow their marriage, there is no other reason why she should be angry with him. Even that is not a convincing reason...
How did she get confined to a wheelchair, if she is pretending, then the accident must have been linked to vansh or Kabir might have lied to her.
