As Arthur watched Merlin fight, his first thought was that he was an idiot.
Then he saw him use a spell to heal Gwaine, who didn't notice what Arthur did: that Merlin had a new cut right where Gwaine's had been.
But the final straw was when he gave the boy they had rescued his blanket, even though he already had one, just because he still looked cold.
Arthur rolled his eyes and threw his blanket on Merlin's head. The idiot may be selfless, but Arthur was not. And he definitely did not have time to find a new manservant.
