The battle is halted by Calchas, who declares that the battle is not fated to end until Philoctetes joins the Argives. Philoctetes had been left on the island of Lemnos due to receiving a bite on the foot from a poisonous water snake that became infected and repulsive to the other Greeks. This scenario draws on source material from Sophocles' "Philoctetes". Philoctetes is rescued from his cave. They tell him that his wound can be healed by the surgeon Podaleninos if he agrees to come with them to Troy. Although Philoctetes considers Odysseus at fault for leaving him on the island, he forgives Odysseus.
