My dear friends did you notice how Aiy Saheb changed her mind everyday? Let me explain you my theory!
Aiy Saheb is suffering of schizophrenia due to the terrible circumstances in which her husband died. One day she's at Naku's side and so she' is a loving and caring mom and second day she's at Kala's side ...in other words Kala ke kaale mansoobon ki BIG BOSS!
Sometimes Aiy Saheb had crisis (these days it's quite often I must say...) and lost her minds (the reason of her collapse) in fact her "badi hasti" side wanna come out constantly but the "caring Aiy Saheb" trying to fight against...this is the reason why she always changes her mind about Nakku and also the proof that she's the Badi Hasti !!!
Sach boloun to Aiy Saheb ka alag hi "Laagi tujhse lagan" show chal raha hai...She doesn't know if Aiy Saheb ko Dutta se lagan hai ke Kala se...So guys LAAGI TUJHSE LAGAN is more than Dutta and Nakusha...It's also about Aiy Saheb's schizophrenia!
