ya, its definitely a dangerous territory..this is most likely his imagination...but if it is real, i think she is just doing this to make him listen to her or maybe she plans to live as dark naku sometimes and fair naku other times so her gets used to her...remember before dutta left he said "mujhay nahi pata tu mujhat apni jhooti shakal kaisay dikhayay gi"..so maybe she has chosen this way to deal with it..
Huma how is this going to serve her purpose.........its again repetitive thing happening.......how can he accept this reality if naku herself wears black color .........she has to make him understand her issues n clear this misconception that she is not dhokebaaz
