Quoting A/N chapter 79:

Anything you think will be completely inexplicable to the readers, probably won’t be - they know less background info than you, so where you see a single huge missing fact you haven’t yet revealed, they see a plentiful bag of possible interpretations. (Discovered when I compared all the reviewers’ interpretations of the Wham Line at the end of 78, to the actual interpretation revealed in 79.) [my highlighting]

Edited to add: I thought that referred to interpretation of "why did Hermione try to murder Draco? Why was she convinced Draco was plotting against her?"

But I see now that it refers to interpretations of the Wham Line specifically. So it more likely means interpretations of "how did Hermione try to murder Draco?" Or even, "what does the accusation that she tried to murder him mean? Did she really try? Or is this a combined Hermione-Draco plot to flush out whoever is manipulating her?"

I take it others adopt the second reading. It's apparently the intended one. I retract my claim.

Thanks for asking me to quote and so forcing me to reevaluate my evidence. Upvoted!
