Run: Season 1, Episode 2

1 - 2: Kiss

During their first night aboard, Ruby's mind is consumed by sex, while Billy probes for personal details she's reluctant to give up. Comforted by the fact that her husband believes she's on a weeklong yoga retreat – and determined to make Billy jealous – Ruby brazenly connects with Derek, a stranger on the train. Meanwhile, Billy works to shake a persistent figure from his past.
