Thinking about the episode over and over again, remembering Razia's words about how Siddique fell in love with Zainab in America I came up with this possibility; What if Zainab is actually alive?
Before any of you look at me with an 'W*F' look and tell me that we saw her get stabbed, I will have to interrupt you and inform you guys that although we saw her getting stabbed, we never saw her face when she was getting burnt. So what if Siddique, who apparently fell in love with Zainab took her out of that burning building, somehow replaced her body with someone else's (IDK how he could have found a body so quick but it's Indian Television, anything could happen) and then took Zainab to the hospital, where the doctors managed to save her?
Zainab then could have contacted her sister and asked to take Zoya away (How she found out Zoya was in the orphanage IDK, I didn't think that far) to protect her child, and then she herself went into hiding so Raziya has no way of knowing that her sautan is in fact alive.
Siddique may not know about his 'loves' whereabouts and for her own safety he decides to not search for her and let her be, he also doesn't know where the child went (as shown this episode)
This way we could actually believe in the whole Siddique was in love with Zainab scenario without having the headache of thinking 'Then why the f**k did he allow his sadist wife to kill her?' it's because she's actually alive and he made sure of that.
Also wouldn't it be wonderful if she was in fact alive, Zoya would finally have a family that she yearned for so desperately.
I know this 'prediction' (If you can call it that) came straight out of the left field, I highly doubt it will come true, but I just can't understand that if Siddique really loved Zainab and wanted to marry her then how does he let her get killed? After watching today's episode it's clear that he loves his daughter, so there is humanity in him and I find it hard to absorb that someone who has tears in his eyes for a daughter he's never known could ever allow the women he loved to get killed.
P.S Wasn't the scene with Siddique and Zoya just beautiful! And the background music ? I had tears in my eye's, and for people who said that Siddique only ever has one expression on his face, I think he excelled today, did you see the look in his eyes? It was a mix between; pain, yearning and hope.
