Ok. First things first. There are two Rehannas.
One is the fic Rehanna. She has a profile in the fanstuff section. Basically, she's the older, more serious one. Also, she's actually related to Vegeta.
The other one is the web Rehanna. That's me. Part of my site is about me, so you can know just how odd I am. I'm a lot bouncier than Fic Rehanna, and have lots of Pocket Bishounen. And I have no widow's peak.
Got that? Here comes the weirder part.
Occasionally, Fic Rehanna will come out onto the web. When this happens, it's very odd. She doesn't adapt very well to doing that. It's always entirely my fault, and annoys her a lot. Not a very wise thing to do, but she can't hurt me. I'm her creator.
And occasionally, I, Web Rehanna, will enter a fic. This is mostly when I do my divine intervention bit, but sometimes it's just for fun. This also annoys Fic Rehanna, along with everyone else in whatever anime I happen to have written myself into.
Are you confused yet? Here's the weirdest part.
Fic Rehanna and I exist simultaneously. We can meet, we can chat, we can spar, we can try to kill each other, stuff like that. She doesn't like me very much, even though her kids do. But, when we are together, nobody is allowed to mention the fact that there are two identical women standing there, otherwise I'll go poof and come back to the web, or Ficcy-chan will go back to the fanfic world. It's a very disturbing feeling, and it's happened before. Not fun.
Actually, this here is the weirdest part.
When we choose to do so, Fic Rehanna and I become the same person through the medium of none other than the Fusion Dance. Neither of us enjoy this; we hate doing that dance. So we do that very rarely. The result of the fusion is Super Rehanna. Very, very scary. Be afraid when we're Super Rehanna. Be very afraid.
