Seeing this scene, Nagris was briefly stunned before turning to Anthony and saying, "He picked himself up by pulling his own hair."
Durken froze, looking at Nagris in confusion, clearly not understanding the meaning. But Anthony understood immediately.
Back in Iron Sand City, Nagris once had a conversation with Anthony, stating that a person couldn't lift themselves into the air by stepping on their own foot. At the time, Anthony stepped on his left foot with his right and flew.
Nagris got furious and then claimed, "No one can pull themselves up by pulling their own hair," but Anthony didn't fall for it. Enraged, Nagris cursed him, saying he'd never have toilet paper when he needed it. From that day on, Anthony never had toilet paper—either he forgot to bring it, or it got wet when it fell on the ground.
Upon hearing Nagris's comment now, Anthony immediately understood. The distant shadow was literally "lifting itself by pulling its hair."
