So, we've entered into a 
non-aggression pact with you people...
...لذا دخلنا في حلف عدم اعتداء معكم
So. Wir haben zwar einen
Nichtangriffspakt geschlossen, …
Sé que firmamos un pacto
para que no haya interferencias.
Sé que hemos firmado un pacto
para que no haya interferencias.

un pacte de non-agression,
Parliamone...
Então, firmamos um pacto de
não agressão com vocês...
Римуру, мы заключили с Темпестом
пакт о ненападении…
