"Superman is about someone trying their best to save the world, one day at a time. And it’s about that person’s love for that one whose intellect and emotion and sheer bloody humanity completes him. It’s about Superman, and it’s about Lois and Clark. And that’s all there is. That is the spine. That must be protected, to the death." - Warren Ellis
Lois: I want you to promise me something.
Clark: Lois, I swear to you, I’ll look everywhere. S.T.A.R. Labs, Cadmus…every advanced civilization in the universe. Someone will have a cure. We’ll beat this.
Lois: I hope so. But that’s not what I meant. If anything happens to me—
Clark: It won’t.
Lois: It might. There are some fights even Superman can’t win. I know you, Clark. You’ll want to withdraw. Wander your Fortress, looking at relics from the past. Lose yourself in your never-ending battle. I want you to promise me not to do that. The world needs Superman. But more importantly…it needs a Superman that understands it.
