"Unfortunately..." Gellert Grindelwald shook his head in denial, a fleeting trace of loneliness appearing in his eyes. "I never taught him that spell."
"The Dumbledore family has always been accompanied by phoenixes, and Albus himself is exceptionally skilled in fire magic. He had no need for me to teach him Protego Diabolica."
