Well, I started liking Lana in season 5, so I feel like I should be defending her, but I honestly can't think of a way she has positively affected anyone in the last 2 seasons. I mean, I suppose from one perspective she's keeping Lex from completely going over to the dark side, but would he be there if he weren't so alienated from Clark?

Unfortunately I don't HAVE magical Kryptonian powers to transport you into the SV verse. And if I did have magical Kryptonian powers I'd be figuring out a way to bend the rules and spend my hour having sex with Lex, sorry. :D I'm not completely selfish--I'd, um, warn him at the end or something.
