i have a feeling that ishita has got feelings for yash right from the moment she saw him.
and then she saw arya having fun for the chocolate and also when yash described about his cute family while telling the reason for stopping the marriage... ishita must have got a clear view of yash's excellent character so i fear she would interrupt arya seeing their happiness
Ishita is deprived of love from her parents who thought her a burden because of her handicap. she is envious of Yash & AArti's relationship, which she thinks could have been her's if yash married her. What she does not yet realize is it takes lot of hard work and determination to make a relationship work in a marriage. All this will take time. But Ishita wants it now!!!!!!
