what is up w/ shalini?

guyz, How da hell did Shalini figure o/ ashmit was ruining da gujrals? i mean i thought only ronit and ashmit knew dis fact...where did shalini come frm?? and i think there is another reason y shalini mite be helpin ronit, and i don't think its b/c she wants badla frm ashmit...dis drama can't b dis predictable, there has to be a secret plan we don't know abt...
