Ciel decides to pay back Maurice Cole for his underhanded trick. Since Maurice lives in a different boarding house, he arranges a special exemption for an acquaintance to be admitted to Weston so that he can monitor Maurice.
I will build a relationship 
of mutual betterment with you.
سأوطّد العلاقة المتبادلة بيني وبينك
eine Beziehung des gegenseitigen
Ansporns zueinander aufbauen,
juro ante san Jorge formar contigo una
relación que nos ennoblezca a ambos.
formaremos una relación sana
que nos ayude a mejorar.
sans jamais nous trahir
ni abuser de notre lien.
finché resteremo
 tra le sacre mura di questo nido,
E, assim, construirei uma relação
de melhoria mútua com você.
Вместе мы станем достойными мужами!
