In the Kingdom Hearts fandom, there's been some ruckus made over an apparent 14th member in the Organization. My first instinct was to say, "Oh, it's Namine." Because even if she doesn't wear the clothes, she could easily count as a member (and I did say that the Organization needed some more women anyway), but then the extra member is described as someone wearing a hood. Speculation says that it may be female.
The problem is that no one knows for sure. Some say it's Riku. Others are not. Blagh. We don't know who it is. Could be Aqua. Plus, the info might not be as accurate as people think. Sure, there may be an extra member, but no one should crying "MARY SUE!!!" at all because no one even knows what the character is like.
That's the fandom for you though. It's fun to observe it.
