had they not shown Samrat reading those letters may be even i would have believed that she is leaving and has left the hope of getting her bro back. But with Sam reading all the Old letters and that too not with anger but with a guilt on his face I feel that she wont leave. So may be today we see this bhai behen ka milap after 20 yrs ka vanvaas(hope my calculation of 20 yrs is right)😉
