Insta-Theory: Just add water
I was very aware that today was the last day of May, because I knew it meant an all-too-rare chance to prove a theory in a matter of hours instead of months or years.
Since Helga Hufflepuff-- pictured holding her golden cup-- became May's Wizard of the month at jkrowling.com, I've had a guess that Salazar Slytherin would be next. We'd see Salazar wearing his golden locket for June, Godric Gryffindor holding his sword for July (Harry, Neville, & Jo's birthdays make July the obvious Gryffindor month), and Ravenclaw with her whatever-it-is in August. Because Ravenclaw will have a relic, and it will be important.
And since it's already midnight in the UK, I got to go to JKR's site and see that I was right! So far. Mostly.
Because June's wizard is Salazar Slytherin, but he's wearing a silver locket.
Huh?
It was definitely gold in Half-Blood Prince.
"See this?" he bellowed at Ogden, shaking a heavy gold locket at him, while Merope spluttered and gasped for breath. [page 207]
This is either some weird clue, or an art mistake. I'm much more inclined to think "art mistake," but there were already people who got the locket material mixed up on a regular basis. (Okay, if I name names... I'm thinking of Spinner's Cast. Apparently I am a big nerd about types of metal, because I kinda twitched whenever the hosts said the locket was silver in the book.) And there were already people who said the locket on the Bloomsbury adult cover looks silver. (I don't get that one at all, 'cause the thing looks plenty gold to me, but whatever. Those people still exist, and I can't tell them what they see.) So now this is going to start off some crazy wave of theories, I just know it.
"ZOMG! There are two lockets!" "ZOMG! Locket alchemy!" Etc.
Also likely to spark some theories is the way Slytherin's holding his hands kinda in the shape of the mysterious Bloomsbury children's cover spine symbol. But that thing is just plain dangerous for theory spawning, so I try not to worry about it too much.
Friggin' triangle... *grumble*
