All right, I know you get increasingly curious the longer you are unaware of some details. But patience is never a bad thing to cultivate. And it's not doing you any active harm, because what you're most eager for, I have no idea about, so it's not likely to affect anything on that front until you do know.

Besides, you know how these things work by this point. Odds are that even if you try speculating, you'll still end up surprised.

So just be patient and work with what you do know. The rest will come in time.
