well i agree its time for ishu to know raman's past and what leads him into such aggressive and ruthless person so that she can help to change him to the better...since she doesn't know anything abt raman's past...whenever she do something nice for raman...it leads into fights b/w both of them...so its time for ishu to know the truth so that she understand him better and make a move according to it
but i don't think simi's case will lead to it...she has her own set of mystery which i think ishu will handle herself w/o any interference from Bhallas and raman...i don't think she will spill the beans to raman...i feel she will help simi secretly maybe simi request it...and this leads into a positive relationship b/w sisters-in-laws...this time round simi cannot be rude to her since ishu have find out abt her mystery...she will have to spill all the beans to her and might even request not to tell raman and family abt it...ishu's humbleness will come out in open when things go out of control and simi herself will spill out the beans by herself...how ishu helped her throughout her miserybut then it all depends what is the situation...what is mystery...its just my predicitionsi feel now nothing can go wrong ishu's favour becos she needs to bond herself with the family and one step closer towards raman's heart...
