Clark and Raya in “Unfinished Business”

Clark

I haven't been the best son.

Your father was hard on himself, too. He felt guilty that he couldn't save Krypton. His only redemption was sending you to save Earth.

Clark

Save it from what?

Extinction. Your civilization is going to destroy itself, just like Krypton. You should know this. It was part of your training.

Clark

I haven't started my training. Now the Fortress is damaged. Jor-El tried to warn me, but I didn't listen. I mean, how could I trust someone who brought so much pain into my life?

Pain is a part of anyone's journey, Kal-El. You can't escape it. You must accept your destiny.
