Shindo agrees to become this creature's representative as it begins its negotiations with the Japanese government.
I will tell the people 
outside what I told you.
.سأخبر الناس الذين في الخارج ما أخبرتك إيّاه
Ich werde den Menschen dort draußen mitteilen,
was ich mit euch besprochen habe.
Le diré a la gente de fuera
lo que les dije a ustedes.
Le diré a la gente de fuera
lo que os he dicho a vosotros.
Je communiquerai aux autres humains 
ce que je vous ai dit.
Informerò gli esseri umani all'esterno
di ciò che ho detto a voi.
Direi às pessoas lá de fora o que lhe disse.
