Looks Like Another Entertaining Rowling Year
JKR: A part of the final battle that made me smile was Slughorn galloping back with Slytherins, (SU: Yes!) (JN laughs) but they’d gone off to get reinforcements first, you know what I’m saying? But yes, they came back, they came back to fight, so I mean- but I’m sure that many people would say “Well, that’s common sense, isn’t it? Isn’t that smart, to get out, get more people and come back with them?”

So the Slytherins came back, eh?

*is laughing so hard the tears are rolling down her face*

Oh, Jo, I love you more than any author out there. You've got an almost Bertie Woosterish talent for spreading chaos among your fans.

But I really think that had better be made clearer in the subsequent edition. I came up with this idea, but I thought I was retconning, not reading the authorial intent properly.

P.S. Have I mentioned before that my (adult) brother, were he to post online, would be prime Fandom Wank material? He said after Christmas dinner that he felt like Rowling was trying to shove her interview canon in his face, and make him accept it, and was telling him to shut up. Also that he wasn't going to give her anymore money. I asked him why he was reading all her interviews, and he couldn't quite explain that. It was great after-dinner entertainment. Particularly when it came out that Harry Potter Seven was the only book he's read this past year. *headdesk*
