Zubi was looking upset in the precap when ahmer was saying things to her.. Seems he got to know something new or was he just telling her off about the lie she had said about umair sadia affair leading to his and sadia divorce. It's not clear
ahmer said na me KADI se KADI milata hu to dekhta hu tum farsh par thi and sadia arsh par.. it means wo stating se abhi tak jo hum sabka link ek karega.
