I think she was sure that Siya will not b harmed. Actually we Indian viewers expect a way too big from a female lead.She is also a human being and mistakes or wrong doings can happen by her too. It was the same Riddhima who was came running to save Siya and vansh injured her with knife. In compare to others,I think riddhima has done less.Originally posted by: Pavi10989
