User blog comment:EmrysOfAlbion/Arthur's Bane Theories/@comment-82.174.238.189-20120927200313

i personally think Merlin is arthurs bane. because he is both his strong and weak point. He keeps arthur safe and makes sure he doesn't get killed. but if they mannage to get merlin away from arthur, he will be all exposed and then mordred can kill him just fine.
