Team Kakashi are stunned to learn that Sai's true mission is to kill Sasuke.  Naruto wants to believe that the smile Sai showed them was real, but there is a possibility that it was all an act.
I don't know you very well.
.أنا لا أعرفك تمام المعرفة
Ich weiß nicht viel von dir.

No te conozco muy bien.
Apenas te conozco,
Non ti conosco molto bene.
Eu não conheço você bem,
Тебя я знаю плохо.
