"And wow, just comparing Lana to the whispering pink thing she was in season 3, and she has actually become a cool character"

Yes! I am so happy with the new and improved Lana. I watched the pilot episode recently and, just... wow. Quite the dramatic change. :)
Hee hee, how great was the line where Lex said that Clark isn't the easiest guy to be in a relationship with. Eeee!
It definitely felt like the Clana was over. And I actually liked that scene. Very emotional. Good job, KK and TW! And of course, loved the final Lexana moment. Can't wait for more Lexana.
