As part of the crew of the Jewel of the Realm, Lewis witnesses the death of Liam Jones and joins forces with Killian, who renames the ship as the Jolly Roger. On a journey to the Southern Isles in Arendelle, the ship is caught in a storm and Lewis tries to keep the ship steady. Lewis eventually leads the ship to Leviathan Shoals where the crew began work on the ship to set sail after the storm. They are greeted by another ship, with an alive Liam. Lewis believes that Liam is just an enchantment made by the mist. They then proceed to leave the shoals, but are attacked by the Leviathan. During the attack, Lewis assures Killian that Liam is just a hallucination as the Leviathan is killed by dynamite.
