Ciel wins the P4's trust, but he still can't find a chance to get close to the Head Master. And so he brings up the subject of Derrick Arden with the P4 and their drudges. When he does, the expressions on the prefects' faces change...
Isn't Derrick Arden 
the Duke of Clemens's son?
أليس ديريك آردين هو ابن دوق كليمينس؟
Wenn ich mich recht erinnere, ist Derrick Arden
doch der Sohn von Duke Clemens, nicht?
Si mal no recuerdo,
Derrick es hijo del duque Clemens, ¿no?
¿Derrick Arden no es
el duque del hijo de Clemence?
Derek Arden,
c’est le fils du duc Clemence, non ?
Se non erro, Derrick Arden è il figlio
del duca Clemens, giusto?
Derrick Arden não é o filho
do duque de Clemens?
Если не ошибаюсь,
это сын герцога Клеменского?
