Daisuke locks Takei up in the basement of the Kambe residence. Cho-san interrogates him to find out who the mastermind is behind all of this, but Takei is shook with fear and refuses to speak. Daisuke discovers that the reason why HEUSC is being uncooperative is related to his parents’ research. Kato goes through the documents that Cho-san gathered in his 19 years of investigating the case and finds an important photo.
Tell him that he's old now, and to take it easy.
،أخبره أنه قد كبر في السن الآن 
.فليأخذ الأمور بروية
Sag ihm, er soll es bei seinem Alter
nicht übertreiben.
Dile que ya es viejo
y que se lo tome con calma.
Dis-lui qu’il est trop vieux
pour faire des folies.
Digli che ormai è anziano, non deve strafare.
Fale para ele que está velho agora.
É para pegar leve.
