yes that was what I have been thinking,a ice breaker between Sadia and Umair cannot be wrongfully rubbed DNA report ,it has to be Aaliya's sickness.I feel going on that trip with Sadia he would get that report,be it over phone call or bumping into the oncologist in the hospital.last epi me umair ne kaha tha k aaliya ki report teen din baad aani hai...precap me umair ki T shirt different hai.. it means next day wo sadia k paas jayega DNA k liye.. May be jab wo hospital jaye aaliya ki docter umair ko dekhkar usko report k baare me batAye and sadia bhi waha ho and usko bhi pata chal jaye.
BTW delivery se pehle DNA karwana risky hota hai..May be umair DNA na karwaye.. is tarah thoda uska character accha show ho sakta hai.
Also I agree yaar why they are not going to go with this angle of risk of DNA test before birth.I agree it would warm audience's heart a bit if he delays it.
