For a second I wonder if Clark thought maybe Lana could be the ultmaite destoryer his father was talking about. The look on his face he seemed worried. Chill dude it's not her so you can relaxe bro. Take her to the north pole and have some more of that super sex!

He looked worried because he knows how destructive and psycho she can be when she has powers.

he looked worried because now he had no excuse to avoid taking the relationship to the bedroom... proof that he has human qualities: performance anxiety :D
