No one expected it to happen, not Optimus Prime, not Princess Celestia, not Twilight, not even Discord! Well, I did, and so did the writer, but they don't count. Anyway, it all happened on a dark and stormy night-oh wait, that's the wrong book. Sorry, it really happened on a not-so dark and stormy night, in space! Wait, what do you mean you can't have night in space? Oh, forget it, click chapter 1 already! (Takes place sometime after the Season 5 premier; teen tag for a VERY little bit of blood later)
