If there's ever a problem within the Empire, 
those feelings could become an obstacle.
إن وقعت مشكلة داخل الإمبراطورية
قد تكون تلك المشاعر عائقاً
Sollte es jemals ein Problem
in diesem Reich geben,
Si le pasa algo al imperio,
eso podría ser un obstáculo.
Si le pasa algo al imperio,
eso podría ser un obstáculo.
Si un trouble survient
dans l’empire,
Se mai ci fosse un problema all'interno dell'Impero,
Se tiver um problema no Império,
esses sentimentos virarão um obstáculo.
Если в империи приключится беда,
их чувства станут помехой.
