Although I wanted to shake up Prachi yesterday, I would'nt entirely blame her for removing the photos from the room. Even if Ayesha had not told her to, I guess she would have removed them because she saw Milsi's reaction to seeing her. When he said he hated her, he held his head and nearly collapsed. If he sees their photo together his reaction would be even stronger considering that he has no inkling of their relationship.
If a known emotion (of disliking anything that belongs to the Shahs) can trigger such a reaction, an unknown emotion (of his marriage to Prachi of which he is still not aware of) can only be guessed. Prachi did not want to take any chances with his life. If you had noticed her expression, she was as mortified as Ayesha was when she dropped the photo and Milsi came in just then. She would not have wanted him to see that photo just then and get into a coma or something.
As to giving it good to Ayesha, if she could not bring herself to slapping Ayesha when she burnt the car, can we expect anything at all from this cry baby? This is the reason I detested an Amnesia track.
