LUKE AND CHRISTOPHER COME TO BLOWS - Luke (Scott Patterson) and Lorelai (Lauren Graham) share a sweet moment when Luke introduces her to Liz's new baby. Christopher (David Sutcliffe) witnesses the scene and it adds to his concern that Lorelai isn't fully committed to their marriage. The next day, Lorelai and Christopher get into a fight over whether they should exchange vows at the elaborate wedding party Emily (Kelly Bishop) is throwing for them. Luke contacts a lawyer over his custody troubles with Ana, then runs into Christopher and the two have an ugly confrontation in the streets of Stars Hollow. Meanwhile, when Logan (Matt Czuchry) discovers that Rory and Marty (Wayne Wilcox) have been pretending that they just met, rather than admitting their previous friendship to Lucy (Krysten Ritter), he reveals the truth to Lucy. Finally, Emily gives Lorelai a warning about her marriage. Sean Gunn also stars. Jackson Douglas directed the episode written by David Rosenthal (#2T7760).
