Things come to a head in Smallville when Kara, a beautiful girl (guest star Adrianne Palicki) with superpowers, who claims to be from Krypton, comes to entice Clark (Tom Welling) to fulfill his destiny. Overwhelmed by her appearance, Clark turns to his parents (John Schneider, Annette O'Toole) for advice but is shocked when the girl forces Jonathan to finally reveal the deal he made with Jor-El. Also, Clark makes a discovery that ultimately redefines his relationship with Lex (Michael Rosenbaum), and Clark's relationship with Lana (Kristin Kreuk) takes a final turn. Meanwhile, Lex turns the tables on Lionel (John Glover) with the FBI.
