Merlin - unslashy? Were we watching the same ep?

Arthur died for Merlin ... well okay, not quite, but he thought he was going to. Merlin chased after Arthur to the labyrinth (nice to know Uther has a big magical labyrinth on the doorstep - found that a little odd) because he didn't want him to go alone. These two are so hopeless devoted to each other I think even Uther might get a clue if they're not careful.
