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.
