me too thought the same dr:)
i think by showing indifference in front of others, sid will try to find the truth
even shruti aka roli tried hard to prove that she is shruti only, not roli
when sid tried to touch her, she immediately started to speak up about rosid pic, watching him for the 1st time & everything
i feel like she is also acting
even in precap, she mentioned roli as simar's sis, how does she know that???
or may be i am thinking so much lol
