Mr. Kirby said:did you ask him about the japenese SD? he hasnt denied it yet.
Yes. He told me to post it in the thread (Since he has a policy against answering questions about the riddle in IM), which I did.
If he doesn't reply to it in the thread, that obviously means that it is, in fact, an SD.
Frankly, I don't know what else it COULD be about. It makes perfect sense as being about an SD - the problem is, we don't know what's in it.
