You know what we have to do. In order for him to control Excalibur, he needs to go to the Darklands.

That's not happening.

[later]

Welcome to the Darklands...

He needs to take the sword to the tower.

Give me another way.

There is no other way. And he has to go alone.

He can't survive the Darklands alone!

You don't want all of him to survive, that's the point. You have to break his old self completely, wear him down. You want him to think big? Give him something big to think about.

You're playing with fire, mage. And I'm not killing the king before he's even become one!
