Scott Wells was also replaced as Lex Luthor by Sherman Howard. The change in Luthor's appearance was explained in the second season opener "With This Ring, I Thee Kill". The two-part episode revealed Luthor had plastic surgery to assume the appearance of Warren Eckworth, the wealthy inventor of the "Superboy Gun", which Luthor believed could kill Superboy. The character of T.J. White was written out of the series (he went to work for the "Daily Planet") and Andy McCalister, portrayed by Ilan Mitchell-Smith, became Clark's new roommate. Andy was very different from T.J. and was constantly looking to make money with his get-rich-quick schemes. He also flirted with Lana frequently and his advances were always refused, though Lana did consider Andy a friend.
