 On the night before Lane and Zach get married, the plans for a bachelorette party go awry, as do the plans made by Zack s buddies, so the two groups end up together for a makeshift party in a vacant parking lot. Mrs. Kim informs Lorelai that she cannot attend Lane s wedding without an escort. Since Luke is still out of town, Lorelai invites Christopher to be her date. Everyone attends two wedding ceremonies, followed by a wild wedding reception in the town square.
