Emily (Kelly Bishop) is upset when her troublesome mother-in-law Trix (Marion Ross) shows up at Richard's (Edward Herrmann) 60th birthday party...especially upon discovering that Trix has rented her house to the rock band Korn. Meanwhile, Rory (Alexis Bledel) tries to persuade Jess (Milo Ventimiglia) to accompany her to Stars Hollow's Winter Carnival, but Jess balks because Dean (Jared Padalecki) might be there -- a contingency that thrusts Rory back into Dean's arms for what seems to be the millionth time. And in her efforts to keep her musical activities secret from her mother, Lane (Keiko Agena) begins her band rehearsals in Lorelai's garage. ~ Hal Erickson, Rovi
