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'll do whatever it takes
to save him.
.فسأفعل ما يلزم أن أفعله لإنقاذه
Ich werde alles tun,
um meinen Freund zu beschützen.
Haré lo que sea necesario 
para salvar a ese camarada.
Haré lo que sea necesario para salvar a ese compañero.
Sappi solo che farei qualsiasi cosa,
Se for para salvar um companheiro,
 farei o que for preciso.
Ради спасения товарища 
я пойду на что угодно.
