The final five pirates remain, and Ben and Christa deliberate on Jay's methods/schemes to remove the captain (Christa) from power. The expedition begins with a swim as the two crews go in search of the Astronomer's treasure. Laurel lags in the swim, slowing Louie down. Ben, Jay and Christa find difficulties along the way, but manage to pull through and win a $30,000 loot. Back on the ship, Jay, Ben and Christa go at each other's necks on the issue of betraying each other and lying. Ben shows his true colors to Jay, and Jay does the same, as Christa goes into a meltdown of emotions.
