Squad 13 heads back to the Garden for testing, with Zero Two's emotional state worsening by the day. They run into Nine Alpha, who offers some insight about her, but the most revealing words come straight from the horse's mouth...
And she can do that because she's 
the key to saving the world.
ويمكنها فعل ذلك لأنها 
المفتاح في إنقاذ العالم
Sie ist nämlich der Schlüssel
zur Rettung der Welt.
Lo hace porque es la clave
para salvar el mundo.
Lo hace porque es la clave
para salvar el mundo.
Elle est la clé
qui sauvera le monde.
E può permetterselo perché
lei è la chiave per salvare il mondo.
E ela tem permissão pra fazer isso porque
a salvação do mundo depende dela.
В ней ключ к спасению мира.
