Evidently, we get to see a Royal Ball in Camelot according to this article. It also mentions that there will be a surprise guest of honor.

Now, if our guess about how Camelot will be included is correct, having Prince Charming as a Guest of Honor would not really be that much of a surprise. I would imagine that we might see the Charmings and the Hoods in full ball regalia (I mean, after all David is a King and Snow and Regina are both Queens. They would fit right in). Merida being the guest would be a little more, but if they stick to her backstory (such as exists), she is a Princess of her realm, so again, not a stretch, and if she's been introduced in Ep 1, then it still wouldn't be much of a surprise.

Comments about the ball or who the surprise guest might be?
