Going by the last few episodes I feel tara is the real daughter.
Notice Maasa's concern for Tara's marriage and how she accepted Nahar-Saloni invitation and came at the right time which further dampened Jiji's plans..
Jiji goes on and on harping abt "royal family" this "royal family " that..It would be the ultimate triumph when its discovered that she has no so called "royal" blood.
I agree Nahr-saloni said Jiji is the real daughter but what if its for some other purpose?(i didnt see this episode only read the update so cannot gauge the expressions of the people who were present)
Any comments!😊
