Sai shudders when he finally meets Sasuke face to face in Orochimaru's hideout. The list that Sai gave to Orochimaru lists the members of the Anbu Black Ops, the corps under the direct control of the Hokage.
Infiltration must be done
quietly all the way...
.يجب أن نقوم بالتّسلّل بشكل هادئ حتّى النّهاية
Wenn man irgendwo eindringen will,
muss man das geräuschlos machen.
La infiltración debe 
hacerse sin emitir sonido.
La infiltración debe hacerse sin hacer ruido.
Infiltriamoci facendo meno rumore possibile.
Uma infiltração tem que ser 
feita em total quietude...
Вторгаться к врагу нужно тихо.
