Hated this story line. Bizarro I liked but not like this. Lana thinking it was Clark. I knew it was going to be bad for Clark and Lana after this. After Clark found out Lana was spying on Lex and had Lionel tortured that was bad enough but this was worse. When I watched this I'm thinking "Lana haven't you learned your lesson yet? Secrets and lies break a relationship. Clark is no longer hiding things from you anymore! What happened to I don't want the past to come between us again and this is our chance to start over? Leave Lionel and Lex alone!!!! What they did to you was horrible yes but Clark is alive and well. Lex and Lionel will pay someday for what they've done but revenge is a dark and lonely road. You don't decide who lives and dies. The ends don't always justify the means. Let Lex be miserable all by his lonesome. Let someone else handle the Luthor family. You're with the man you love. Build that relationship!"
If you go to the part just after Julian meets Lionel in Lionel's office, the part where Lana is talking to Clark. Lana is holding two pieces of paper that are medical files. If you pause to look at the both, the first one has the famous made up name "Jane Doe" and as she flips the page the second one says, "John Doe". Go check it out for yourself!
