Just one more thing about Lana...(teeny weeny insignificant spoiler)
She should wear glasses more often.
1. It doesn't make her look as squirrely.
2. It actually makes her look more intelligent, and not in a book smart way but in a she's a grown woman who knows what she's doing and doesn't need a whiny alien to fulfill her purpose in life. Without the glasses, she just looks like the pretty pretty girl in pink who doesn't know when she's outstayed her welcome.
3. She looks like she means business. She kind of adopted a different persona. Instead of looking like a young woman *trying* to catch the bad guy, she looked like a grown woman who would stop at nothing until she brought Lex down. THAT Lana I would like. You know, if she had a little more personality...
