Emily Says 'Hello'

S5 E9: Rory decides that she and Lorelai should split up at the next Friday night dinner and confront Richard and Emily separately about ending their separation. However, Emily dashes their hopes of a reconciliation by announcing that she is ready to begin dating. Meanwhile, Lorelai invites Christopher (recurring guest star DAVID SUTCLIFFE) for lunch at the inn, unaware that Rory had warned Christopher to stay away from her mother. Feeling guilty that she hadn't told Luke about seeing Christopher, Lorelai confesses that they had lunch, and Luke tries to convince himself that he isn't jealous.
