Trisha saw ishita leaving in a hurry and she was tensed..
Mihir saw ishita leaving for office in the morning when he was talking to trisha so he knows the exact time when she left so they can compare the msg timings n the timings at which ishita left..
Everyone was trying to call ishita n her mobile was switched off so howcan she text param
Most importantly ishita never lies n she is a well reputed girl
N one thing when everyone was there the whole bhalla family then where was rinki... I think that there is some mystery behind rinki ...
