We need to cautiously 
observe and act, Koichi.
علينا أن نراقب بحذر ونتصرّف على هذا
‏الأساس يا كويتشي
Wir müssen hier mit Bedacht vorgehen
und geplant agieren, Kōichi.
Debemos observar con mucho
cuidado antes de actuar, Koichi.
Debemos observar con mucho

Il faut procéder prudemment
et être attentif.
Prima dobbiamo valutare bene
la situazione, Koichi.
Precisamos observar com cautela
antes de agir, Koichi.
