I don't remember enough about Smallville to recognize the changes (and probably missed a bunch of stuff about Lana in the later seasons that I stopped watching), so I can't comment on that. Were Clark and Whitney friends? I don't remember that being the case. I like that they quickly recognized the influence of the necklace and thought to get it away from him, but his explanation did seem a little fishy - I doubt Chloe's going to just let him have that one.
