So Lionel wins in this episode. He gives Clark the key so that Clark, not so brilliantly, ends his friendship with Lex. He succeeds in destroying Lex's only true friendship. Then he has Chloe killed when her safe house inexplicably blows up. Then he succeeds in poisoning Lex. Why didn't anyone notice that Lionel was the bad guy in this episode? He destroyed a lot of lives. Lex had stopped his research into Clark long ago. Rating 1.
