Lana Lang Quotes

Young Lana: Do you want to make a wish?
Martha: I would love to make a wish.
Young Lana: Okay. Abracadabra.

(to Clark) Sometimes I dream I'm at school, waiting for Nell to pick me up. But she doesn't come, so my parents drive up. They're not dead, they're just really late. Then I get in their car and we drive back to my real life in Metropolis. That's usually when I wake up. But for a minute, I'm totally happy, until I realize I'm still alone.
