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...
Ugh! One younger sister 
is annoying enough for me.
أخت صغرى واحدة تزعجني بما يكفي
Was?! Mir geht ja schon meine eine
kleine Schwester auf den Geist …
Cielos…
Si una sola hermanita ya es molesta…
Uf, yo con una hermana pequeña
ya tengo más que suficiente.
Eita! Uma irmã mais nova já é
irritante o bastante para mim.
Жу-у-уть! А ведь уже от одной сестры
никакого покоя нет!
