Albus needed to make a comeback, but how? Everything he tried, didn’t work. He tried to send letters to the boy to express his disappointment and every time, he received a one-word-answer with a fat Japanese "No". He hated being denied and then, there were the Kurusu parents. They even had the audacity to threaten him with charges of harassment. Albus didn’t like being threatened like that, but he was going to deal with those muggles.
