Professor Albus Dumbledore: "Lily... after all this time?"
Professor Severus Snape: "Always."
I can't say I knew a lot of his acting background, but goddamn, Snape was by far the most moving character in any movie I've ever seen, what a heartbreaking performance in the last movie, and you can't help but agree with his every move and feeling in the whole series after seeing it.
