I can see how it can be read that way. I think I could accept that reading if it had been even partially in Draco's POV. There was too much Harry moping in Draco's bed for my brain to wire into a gen reading.

I read DDG first, and didn't read any of her other stories until a few months ago, so that may have effected my interpretation. I also didn't really understand her significance as a fandom figure until a few months ago, after I'd already read the bulk of DDG and QoM wips.

I certainly don't think stories need to have a stated purpose/intent that they fulfill. If things change as a part of the organic process of storytelling, then I have no issue with that. Not at all. It makes things interesting. My issue with QoM is that the body of the text and ending was a mismatch.
