I thought it was a great episode! The Bizarro thing was a total surprise, I did not see that one coming.
I really hope Chloe isn't dead. The healing tears are very phoenix like, so I can't help but wonder if she will have other phoenix like powers.
It doesn't seem like we could possibly be done with Lana so eaisly as a simple car bomb. I think she staged it. I don't believe Lex would have killed her. He is capable of a lot of evil, but I think that in his own twisted way, he really does love Lana.
