Smallville - Ageless (4.20)
Clark: I’m from another planet. I’m not even human. Who knows if I can have kids?
Martha: Clark, your father and I couldn’t have children. We were still blessed with a son. You never know what the future will bring you.
Smallville - Scion (10.16)
Clark: I have a new found respect for my Mom and Dad. I always knew that my powers could cause harm if I misused them. But I never appreciated the responsibility they must have felt in raising me. If they hadn’t been such amazing parents, this would could have been a much darker place.
Lois: Luckily they brought out the best in you. I’m sure when we have kids of our own. You’ll be an amazing father.
