Clarks expereinces with Lana only will teach him, that lieing to people you claim to love, will only lead to sadness. besides smallville somewhat takes clark kent and Lang Langs relaitonship way to far. In the comic and every other version, Clark and Lana dated in highschool, and clark told her abut his powers after they graduated form school [post crisis]. In the silver-age Lana was not interested in Clark at all, but had a thing for super-boy [sound famliar]. Smallville takes what should of been a highschool crush/relationship and turns into this long drawn out soap opera. Smallville makes it impossible for us to beleive clark kent will love anyone else ever, as he is completly infatuated with Lana Lang.
