The movie "Victoria and Abdul" shows the history of a unique friendship between the most powerful queen of the British Empire and a lowly Muslim servant from India.
At one stage, Abdul tells Victoria that "she is the most special person in his life, even more than his wife":
Abdul: When I first came to England, I was terrified of you. But you're a very kind lady. You're a very unique lady to me.
Victoria: And you are very, very unique to me, Abdul.
Abdul: I know that you are much older than me, and you are the Queen of England, and the Empress of India, and I'm just a humble munshi. But I think you are the most special person in my whole life. Even more special than my wife.
Victoria: You're married?
Abdul: Of course.
Victoria: Where is your wife?
Abdul: In India.
Victoria: why didn't you tell me you were married ?
Abdul: I didn't think it mattered.
Victoria: Well, of course it matters. It changes everything. You must return to India immediately. And bring her back at once.
Later on, Victoria brings it back again, saying that Abdul really hurt her by not mentioning his wife:
Victoria: I promoted you in the face of considerable opposition and disquiet from the Household. I even turned a blind eye when you failed to tell me that you were married, which, as you know, came as quite a surprise.
Why is she so upset about it? Was it because she had some romantic feelings towards him? Seems unlikely, judging by her age (around 80 at this stage) and the fact that she still deeply loves her dead husband Albert.
