The ship is still as there is not enough wind to fill the sails though a small breeze blows the array of charms hanging like chimes. EXT. SHIP'S DECK, NIGHT The pirates climb aboard and are greeted by another. PIRATE 1: What's wrong? PIRATE 2: Man wounded.

Rory receives a cut, and Amy and the Doctor keep him away from the Siren. Discovering that the Siren uses reflection as a portal, they rid the ship of any reflective surfaces. When Rory and Avery's son Toby are taken by the Siren, the Doctor, Amy, and Avery prick themselves and the Siren teleports them on an invisible alien spaceship which occupies the same spot as the pirate ship. There they find a sickbay where Rory and Toby are kept; Amy and the Doctor pull Rory off life support and Amy performs CPR to revive him.<extra_id_1>
