V for Vendetta/Fridge

Fridge Brilliance

When V shows Evey his rose garden for the first time, she asks if there's a rose for Mr. Susan. V replies, 'Oh no, for him I have cultivated a very special rose.' It took me a few read-throughs before I realized he was referring to Rosemary Almond, and another read-through before I realized that this meant that V was probably responsible for everything awful that happened to Rosemary - the death of her husband, the government refusing to give her widow's pension (after all, he can hack into FATE, who says he can't change those records), probably even arranging that the only job she gets is as a dancing girl. V deliberately arranged for Rosemary's life after losing her husband to be as horrible as possible, to expose to her how privileged she had been, and the lie that she had lived - as well as how truly corrupt and vile the Susan administration could be, and to give her the motivation to kill Susan. In other words, V really did cultivate a very special rose for the Leader.

In V for Vendetta, there's a scene where Evey tells V that she doesn't want him to die, and he replies that that was the kindest thing he could have said to her. It took me a few viewings to realize that it was because she knew nothing about V, and that he was the personification of everything for which he worked, that it meant so much to V (he could rest assured that she would continue his work). She had fallen in love with an idea, not a person.
From the sketch: the scene where Sutler unmasks V, only to find that the terrorist is actually himself. Brilliant because in a totalitarian system, the government is the one that's terrorizing the people. Also the fact that they both order the soldiers to open fire, and end up dead - a totalitarian government essentially destroys itself.
