Humeira's doubt

Humeira is right in her place in doubting Zoyaan because no devar & bhabi will hug like that. So to clear the doubt I would like Humeira to fall ill and according to doctor they will need to operate her and blood is urgently needed or a minor transplant. Then comes Zoya as the only savior. She will not even come to know that she is helping her own sis but doctor will tell Gaffoor that a close blood relationship exists between Hum.. & Zoya. Now Gaffoor will start believing that Zoya is his daughter and he did not know that Razia knows the truth. Out of fear that if Razia comes to know about the truth she will do harm to Zoya as she did to her mom. Now Gaffoor will start liking Zoya and will do anything for her happiness.
