Lair of Lex. Lex pours himself some Scotch. Papa Luthor comes in. He asks if Lex is striving for complete isolation. He says that's dangerous and that no man is an island entire of itself. Lex says he tried to use the private jet the other night, but Papa had taken it to Washington. He asks where Papa went. Papa says he had some catching up to do. Papa tells Lex that he got some info from the Department of Domestic Security. "There's a new girl in town," he says, "and apparently you are fascinated with her." Lex plays it off like he's not really interested in Kara. He says she only works for him at The Talon. Papa mentions Lana, who also worked there. He asks Lex if it's not time to give up this fixation with Clark and everyone connected with him. He knows! Lex asks if this is his fatherly advice for the day. Papa asks if he can't just take an interest in his son's well being. "Oh, which son is that?" Lex asks bitterly. He says Papa spends as much time protecting Clark as he does pushing Lex away. Ouchies. He asks whose father Papa really is. "I wish I could say yours and be proud," Papa Luthor says. Daggers! Coming out of your mouth! Painful! Papa starts to dig in on Lex's treatment of Lana. Lex says he learned from watching Papa Luthor and his mother. That shuts up Papa. "I was just...being a Luthor," Lex says. Papa warns Lex that he's crossed a line. Lex says that Papa may assume the worst, but that he's not that person anymore. Papa says Lex hides his illicit projects like an expert. Papa crosses to Lex and says that he may fool himself and others, but that he can't fool his dad. He chuckles. "You can never fool me," he warns. Lex is at a loss for more words.
