To cheer up Rory (Alexis Bledel), who is brooding over the absence of Logan (Matt Czuchry), Lorelei throws an intimate party with an Asian theme. But Rory's depression only grows deeper, especially after she learns about the midnight tryst between her mom and her biological father Christopher (David Sutcliffe). Luke (Scott Patterson) isn't happy about the Lorelei-Christopher situation either, and he makes no secret of his anger. Elsewhere, Lane (Keiko Agena) returns from her train wreck of a honeymoon in a seminal state of pregnancy. ~ Hal Erickson, Rovi
