Gabrielle causes a prison riot while visiting Carlos, Lynette learns that Parker has an imaginary friend, and Susan helps Mike search for Zach.

On the night before Lane and Zach (recurring guest star TODD LOWE) get married, Lorelai and Rory's plans for a bachelorette party go awry, as do the plans made by Zach's buddies, so the two groups end up together for a makeshift party in a vacant parking lot. Meanwhile, Mrs. Kim (recurring guest star EMILY KURODA) tells Lorelai to bring an escort to the wedding. Since Luke is still out of town, Lorelai invites Christopher (recurring guest star DAVID SUTCLIFFE) to be her date. Everyone attends two wedding ceremonies--one Buddhist and one Seventh Day Adventist--followed by a wild wedding reception in the town square.

Melinda encounters the spirit who died during a sorority initiation ceremony while searching for a girl that's gone missing in the same manner.
