Harini and I discussed this in the morning but how old was Humeira when Zoya's mom died? If she was an infant, I doubt she would be affected but as a toddler- yes, certainly! I wonder if the Cvs are thinking on these lines but if they are, that'd make it really interesting
Zoya was three or so when it happened and I am assuming humeira was one at the time so as you said I am not sure how traumatized she would be even if she dd witness it. But we don't know how the subconscious works so maybe it plays a role. Or maybe humeira witnessed another crime which was committed in a bid to keep the murder hidden?
