Funny should you mention this instance of episode order. Episode files contain information about their position on the list, and The Secret Files episode is actually nearer to the bottom according to it, but JJ2 TSF has a special exception in the code that forces this one episode onto the top of the list by overriding its actual position. I don't know what happened there, I wouldn't be surprised if it were a piece of leftover debug code meant to make testing faster, but while rewriting the episode list I came to conclusion everybody is used to it by now and it won't hurt to keep it.
