JD's killing at the marina spreads renewed fear around. The fainting sheriff and papers found in JD's pocket fitting a partially burnt journal ultimately make Aby realize that she may be the key, as her mother had an adulterous child, probably her. Even Sully, who decided against sneaking off the island, now openly questions her role. Shane is brought to the fold by prime suspect JD's death, so henry can assume charge. Only Trish, who agreed to wait for the state police, sneaks off by stealing Shane's truck. Meanwhile the boys and Abby find and penetrate a tunnel system from the Prohibition era. Splitting up inside, they find Beh's corpse and the room where Madison stayed, according to her told her abduction was a game.
