First the CIA, now the Directory: Everyone seems keen on controlling Excalibur.
After the mission in Algiers, it seems as if the Directory thinks they can dictate when the team can eat, shit, and sleep, and none of them likes it one bit. Arthur is willing to play their game only so far, but after he learns that Mister Smith is sitting on a mission that puts people in danger, he decides that he's had enough, and now it's time to teach the Directory just who's in charge. But the matter of magic is still in question, and Merlin needs to make a choice.
