Meanwhile, trying to distract herself from the issues in her marriage, Lorelai joins Sookie in focusing on the funeral of one of Michel's beloved dogs. After Christopher (recurring guest star DAVID SUTCLIFFE) returns ready to talk, he and Lorelai discuss the main problem that has haunted their marriage: Lorelai's feelings for Luke.
