Even i noticed the same thing about the nails/ hands, and they showed the maid in the back when Asad was yelling his head off at Zoya and from wht i could see, she was looking sympathetic. I also feel that the maid is going to speak up, but asad will not believe her. Then Zoya will start investigating and i hope tht once she finds all the proof she throws them on asads face. I really think its hight time now that Asad has a moment where he remembers ALL of the horrible things he has said to Zoya.
