I'm so glad the CVs gave a continuation scene, it was beautifully done. Aaliya was still reeling from what happened but there was Zain to console her and be her rock. He is not going to let his love go nor is he going to let anyone hurt her, same can be said for Aaliya who was ready to cut all ties with Zubair if it meant holding onto her love. I know she was shown continuing to keep in contact with him after saying she wouldn't but I believe that is only because Zain trusts her and understands the relations she shares with Zubair are completely innocent.
Zain and Aaliya are in this for the long run just like Farhan said. These two will not be shown separating after CVs laid such a strong foundation to their relationship these past few weeks. It is going to take more than a new entry to break these two apart, if Suraiya and Bobby failed to do it then what can this new entry do? Remain optimistic and lets see how the track plays out :)
