I like the slow build to that searing scene in the lift, the differences our boys have to work through, the ending. But I absolutely love the Harry - Ginny scene, Severus goading Harry to do something with his life, albeit in a very Slytherin fashion, and Harry responding to his goading. And Harry finally working out what the problem was, and, as I said, that lift scene! Beautifully written, and lovely dialogue.
