Merlin and Arthur in “The Changeling”

I've brought you your ceremonial sword.

Is that for me to fall on?

Hopefully not. What's wrong?

You wouldn't understand, Merlin. You have no idea what it's like to have a destiny... you can't escape.

Destinies are troublesome things. You feel trapped? Like your whole life has been planned out for you and you've got no control over anything and sometimes you don't even know if what destiny has decided is really the best thing at all.

How come you're so knowledgeable?

I read a book.

And what would this book tell you? Should I marry her?

It's not really my place to say, sire.

I'm asking you, it's your job to answer.

If you really want to know what I think? I think you're mad. I think you're all mad. People should marry for love, not convenience. And if Uther thinks an unhappy king makes for a stronger kingdom, then he's wrong because you may be destined to rule Camelot but you have a choice... as to how you do it.
