“When the owner of the four-leaf grimoire is filled with despair, the five-leaf clover grimoire will be born.” Patry is filled with despair after learning he had been manipulated by the devil all this time and turns into a dark elf. He then starts attacking Yuno and Asta, fueled by nothing but hatred and malice. Somehow, becoming a dark elf had made Patry even stronger, which gives Yuno and Asta an even harder time fighting him. Then Captain Nozel appears before them. Nozel happens to have the best magical attribute to fight against light magic, mercury magic.
I'm surprised you can manage that, 
after spawning that giant demon
أنا متفاجئ لأنّك لا تزال قادرًا على 
،فعل ذلك بعد إحياء ذلك الشيطان الضخم
Deine Seele ist noch instabil,
nachdem du den Dämon beschworen hast.
Pese a que tu alma está inestable
tras crear al Demonio,
Ton âme est instable
parce que tu as engendré un démon,
La tua anima è ancora instabile, 
è impressionante che tu riesca a fare questo
Estou surpreso que você ainda consiga fazer
isso após gerar aquele demônio gigante,
И ведь ты породил демона,
и душа сейчас нестабильна!
