did he "really" not know what the symbol means? because that would be just the most stupid thing Clark ever did. the girl basically told him that she will not lie to him and he still managed to lie. I know he had a secret to keep but keep on lying to Lana was becoming NOT funny at all... BUT still the girl loved him with all her heart... and still do no matter where the show goes from now on....
He knows about the symbol. I don’t believe he knew what it meant at the time. However, Weather Clark was lying or not. Lana’s looks project she believes he does. Clark has said it before, there are things he doesn’t even know about himself.
