Eric, Jackson, Melissa and Abby set off on their expedition to around the island's coasts, hoping to find the captain's party or a way out. Even without the camp's procedures, decisions must be made, which somehow works out. Back in the camp, Lex finally blames his step-sister's self-righteous errors for breaking up and refuses to listen to her anymore. Lex also questions if staying behind isn't another wrong choice, and leaves to join the expedition quartet. The others catch up, and Taylor persuades him to stay in the camp because he alone can keep their quartet balanced.
