Treader concerns the personal growth of Eustace, as he is drawn into Narnia and aboard the eponymous ship along with Lucy and Edmund, and into adventures that bring him to realize how self-centred his attitudes are. Part of the story is told with extracts from his diary, where we see how skewed his point of view is. He describes the ship sailing in perpetual storm (though the weather is fine), and portrays the others as foolishly denying the supposed rough seas and refusing to face the "truth" of the situation. He complains when Lucy is given Caspian's cabin, and comments to the crew that giving girls special treatment is actually "putting them down, and making them weaker". Moreover, he cannot accept that he is in the Narnian world: he imagines that he can "lodge a disposition" (or "bring an action") at a British consulate or a British court; and he is beaten by Reepicheep for treating the mouse as one might a circus animal. Eustace wanders off by himself when the ship puts ashore on an unexplored island. He falls asleep on a dead dragon's hoard and finds himself transformed into a dragon by "greedy, dragonish thoughts" in his heart. He also finds himself in constant pain from Lord Octesian's arm bracelet, which he put on as a boy but is too small for a dragon's leg. Upon return to the Dawn Treader, he is nearly attacked by the crew until Lucy asks if he is Eustace, to which he vigorously nods his head. Being a dragon changes Eustace; instead of behaving like his usual sulky self, he helps the travellers find food, shelter, and a tree to serve as a new mainmast. The problem comes when it is time to leave the island, as the ship cannot hold or maintain a dragon. Reepicheep displays sympathy to Eustace's plight despite the boy's prior cruelty to the mouse and they eventually become friends. Eventually, Eustace meets Aslan, who returns him to human form by peeling off his dragon skin and sending him into a refreshing bath. Edmund shares his own redemption story with Eustace, observing that "you were only an ass, but I was a traitor." Eustace improves after this, and becomes a valuable member of the expedition. When the ship is in danger of being sunk by a giant sea-serpent, Eustace attacks the monster, using only a sword. When Eustace
