Chill guyz! I don't know why, but still I feel that Asad will get to know the truth in the hospital itself. We were told that there would be a fire attack on Zoe and Asad would faint while saving her and eventually, Zoe will save him. Now we see through this video footage that billi is in hospital with burnt hands. So, if we try and connect the dots, we can hope that billi will start fire to harm Zoe, Asad fears something will happen to Zoe, billi could be caught red handed at this point but since the CVs are so much in looove with her, she wont be caught. So, in order to become a saint infront of Asad billi might risk her life to save Zoe and in the process might get her hands burnt. Meanwhile, Zoe might sense something fishy about billi. Then, coming to the slap, there are 2 possibilities. 1) Asad himself will get to know about billi either by overhearing doc-billo convo or might come across some evidence, then slap her, propose to Zoe etc... OR 2) Zoe, might turn on her detective cap and find evidence and proove billi to be the culprit infront of Asad, Dilshad, Najma and Zeenat appi. This will twinch Asad's anger on how can someone close to him backstab him like this and most of all how dare billi try to harm his love Zoe, which will make him slap that billi and kick her outta his life! Then comes his proposal, this time without any stammering, no hichkichies, without getting stuck, he'll go down on his knees, apologize for accusing his Zoe for whatever that was done by billi and say the three magical words! I hope the story progresses like this. What do you say guyz?
