Brooke and a test kit tell Lucas they're expecting a baby. Jake still refuses Nikki any part in Jenny's life. Nathan tells Haley he doesn't understand she won't share his bed but tattooed his jersey number on her backside. After 15 years Keith proposes to Karen, who 'isn't ready', and decides to leave. Dan tells Lucas not to let Brooke ruin his life as Karen did by having him; and bursts in at Nathan's to tell him the beach-house will be waiting 'when' he hits rock bottom.
