As the temperature drops, Alfred decides it’s too cold for him to do his job (collecting life vests and floats). Instead, he marches through the ship singing to himself. A fellow soldier notices Alfred’s hands and suggests he go to the infirmary. Alfred likes this idea, as it will let him spy on Joana.
Once again, Alfred demonstrates his selfishness. Instead of doing his job, which would help other people later on in case of disaster, he only cares about this own comfort.
