I am not thinking of Rajeev or gurpreet at all, I mean to say only that the character of sujal has died. Even Veena believes what he did was sick. Now when he gets his memory back, what will kashish say, "Sujal you took advantage of a woman in a drugged state. By luck it was me. Agar koi aur hoti to...."
Like I said, its a question of ethics.
