The funny thing about ‘A Servant of Two Masters’ is that Merlin could have easily used magic at any time and kill Arthur because he spends that much time alone with him and Arthur trusts him that much, which is the problem, because I think a part of Merlin was fighting the spell and trying not to kill Arthur.
It’s why I think Merlin knows Arthur hugged him when they found him, since it was Merlin who walked to Arthur and smiled.
All of this to say Merlin’s first reaction in seeing Arthur after a long time even under enchantment is to hug him.
Canon material, folks.
