Red was a wonderful Clex episode! In the latest SV magazine it has an article/timeline about Clex called The Farmboy and The Billionaire: The History of Clark and Lex and the writer of that article mentioned that it was Lex that noticed that something was different about Clark! How some claim that Lex has been evil all along and not trustworthy never saw this episode or heard about it, because Lex could have easily taken advantage.
