as a character Manjari contradicted two qualities of Meet H ..
she refused to cut her hair ..( waise reason b koi solid ni ta .. acting hi to krni ti uske liye baal katne ki kya jarurat… also even if she is real Meet H, she wants to fool Masoom and others and this is her disguise… )
she left the house …seriously she literally left the house … (Meet H kitni dheet hua krti ti usko ghr se b nikal dia to b ni gyi… ye to phle chance pr nikal li … well again Meet H ka rishta ta … iska kon sa rishta h… she was right that koi udhaar na liya usne jo chilla ra h us pr )
If she is Meety, her main motive is to get to Manushi and Masoom. Yeh get up unhe convince karne ke liya bhi toh zaroori hain warna yeh dono zaroor Sawaall uthayagi ki Agar Meety nhi hain toh itna Saab kyun kar rahi hain.
Again if she is Meety, she knows her position and she knows she will be brought back.
