Lana: Which part? The immaculate tattoo, the fact that I seem to be harboring a 16th-century witch, or that Jason and Lex took off with a map to uncover it all behind my back?
Clark: Why would they do that?
Lana: I don't know, but Jason said that we were gonna figure this out together. But it turns out he has a rather limited definition of "we."
