thinking about. how merlin brings out the best in arthur and on the other hand arthur brings out the darkest parts of merlin. how arthur always tries to be better and do the right thing because merlin believes in him and he wouldn't want to disappoint him. because he believes merlin is good and he wants to be good for him. how merlin always ends up making the worst decision in his desire to protect arthur, doing things he never thought he'd do. how from saving arthur's life because that's a right thing to do, he goes to putting his life above any of his own morals.
