It just sounds so similar to the finale of episode 3 :/ As you say, what will it TAKE for Merlin to reveal his magic? Is anything ever going to be serious enough?

I don't know, maybe they're going to spring a reveal on us but I am now thinking they won't (or not in this finale at least) and I just cannot believe we will go into another hiatus without Merlin acknowledged, especially if Arthur is now King and Gwen, Queen.
