My comment from fanfic.net:

I loved the chapter- there was nothing wrong with the previous two, but this the mixed bag of very good stuff pointing in multiple directions that I hadn't realized I was missing. I'm talking about psychological/philosophical/emotional material more than the potential plot twists.

I've suddenly realized that this is a chapter in which almost nothing happens in terms of physical action- it's all talk and thought and emotion (and a bit of humming), and it's incredibly engrossing.

Is Hermione's inability to think that she might have been bespelled part of the spell, or normal psychological reaction?

Would fake memories have the same kind and amount of detail as real memories?

Harry saying that the first year girls should put their reputations on the line about Hermione is so perfectly Harry...
