Clark Kent, Martha Kent and others in “Unfinished Business”

Clark Kent

Dad, when that serum got close to the kryptonite bomb, it reacted the same way as my blood.

Martha Kent

So you're saying the serum...

Clark Kent

I know. It sounds crazy, but I think that Lionel Luthor has found a way to use my blood to bring people back to life. If my blood can save lives, maybe I should come forward. What if there's something inside me that can repair dad's heart permanently?

Jonathan Kent

Clark, your mother and I both know that you are gonna save a lot of lives in this world, even more than you have any idea.

Clark Kent

The only life I'm interested in saving is yours.

Jonathan Kent

You do. You save my life every day that you're with us. And we wouldn't trade that for a single moment without you.
