Tannu fed something to Zoya I guess

From the precap I felt Zoya is feeling dizzy and is not in a state to reply to Moulabi's questions...Tanveer was smirking on the other side..so she might have given sleeping pills kind of thing in zoya's drink or food so that Zoya does not get success in marrying Asad...if I am wrong then why Zoya was behaving like that... I guess Rashid might spill the bean to Dilshad about Tannu...I wish Tannu's secret be out soon though zoya and Asad union takes place or not.
