Sewer!

The arrival of Maya's old college roommate Erin leads to an incredibly crazy situation. Maya tries to compete with her friend's globe trotting journalistic ventures by spending a night in a sewer in hope of getting her first hard-hitting news story in a year. In the meantime, Erin takes a break from her hectic schedule and has an affair with Elliott. Adding to the craziness is Jack's surprise birthday party, with Nina and Finch supplying his boyhood idols, crazy old Cowboy Pete and his orangutan sidekick. In the end, though, it's Maya who provides the biggest surprise of all.
