I shouldn't have to say this 
about being in the city,
،لستُ بحاجة لذكر هذا بما أنّنا في المدينة
Sie könnten sowohl in der Stadt
En pleine ville comme à Eden,
nous ignorons qui nous observe.
Potrebbero esserci occhi ovunque, 
non solo qui in città, ma anche all'Eden College.
Nesta cidade,
И не только в городе.
