I also noticed that in the scene of Merlin clambering through the caves after Gwaine gave him the sword, he conveniently has a torch from goodness knows where and the sword wasn't visible even though he had nowhere, like a sheath, to keep it. And then it reappears when he attacks Morgana. So unless he shoved it through his belt on the opposite side from the camera I have no idea where it went.
