Looking for a fic
I just remember this one scene. The Knights and Arthur are meeting the druids, Merlin 8s obviously with them and then the druids recognise Merlin as their king. Arthur is hella shook. And then something goes wrong and Merlin BAMFs out. And then Gwaine says something like, "this is why the neighborhood kingdoms don't f*ck with the druids anymore, be ause if their sovereign". Arthur is super flustered and Gwaine teases him, indirectly indicating that Arthur had a crush on Merlin.
