Justice League Unlimited, Season 1

[On Krypton; Kal-El is with his son Van-El on the roof of his father's lab, as Van looks through a telescope]

Van-El:
Dad! [The ground shakes] Dad? You've gotta look at thi- [Sees Kal-El's troubled expression] What's...what's the matter? Why are you -

Kal-El:
Van, when you were born, it was the happiest day of my life. When I first saw your beautiful little face, your tiny fingers squeezed my hand so tight, like you never wanted to let go. I've watched every step, every struggle...I-I've... but, Van...[eyes begin to water] oh, Rao help me... but I don't think you're real. I don't think any of this is-is real..

Van-El:
Don't say that, Daddy...please, you're scaring me... [hugs his father]

Kal-El:
No, no, I don't want to scare you, Van. You are everything I ever wanted in a son. This...this is everything I ever wanted in a life. But I've got responsibilities, Van, and I...have to...go now...

[Hugs his son as Krypton begins to tear itself apart, and kisses him on the forehead]

Van-El:
[Tearful] Daddy...

Kal-El:
I promise you... I'll never forget.
