In the movie's end, when everyone removes their masks and you see the faces of the people who who were killed, including Evey's parents, Gordon, the little girl... and Ruth and Valerie, all smiling in triumph.
"Is it meaningless to apologize?" "Never."
Evie, having come to accept what V is trying to get across, muses that the letter from Valerie has lost some of its touching effect since she knows it's from him...

He received that letter from the real Valerie years ago, and he never forgot it.
When you juxtapose this scene with Evey's opening soliloquy, it's even more poignant. Ideas are necessary for revolution, but people, and people's hearts are necessary for it to win.
Evey: And it is not an idea that I miss, it is a man... A man that made me remember the Fifth of November. A man that I will never forget.
Even though he kidnapped her, V was nice enough to make Evey breakfast.
