Summary
Analysis
The lifeboat drops into the sea. Klaus cries for the Poet who jumps into the ocean behind them. Florian stands to dive in after him, but the boat is thrown by a wave and he stumbles before he can attempt a rescue. Florian reveals the Poet tied a sack of coins to his belt and gave his life jacket to Florian, dying so that Florian could live.
The Poet sacrifices himself so that Klaus, Florian, and the others can live. Even though Florian knows that the Poet jumped into the water intending to drown, Florian cares so much about his friend that he is willing to dive in after him.
