Frederica is gradually backed into a corner by Elsa's attacks. Then Garfiel rushes to the scene with a silver shield on each arm. The siblings' reunion after so many years is cut short when Elsa's knife violently clashes against Garfiel's shield. Meanwhile, Subaru heads to the forbidden library where Beatrice is. She's surprised when he enters the library and tells her that, after she spent 400 years there under a contract that might as well have been a curse, he's going to get her out.
And how does the enemy know 
that weakness, I suppose?
،وكيف يعرف العدوّ نقطة الضعف هذه
على ما أفترض؟
Und warum kennt der Feind diese Schwachstelle?
¿Cómo es que el enemigo
conoce ese defecto?
¿Cómo es que el enemigo
conoce ese defecto?
Tiens donc…
Et comment serait-il au courant ?
E come fa il nemico a conoscere
questa debolezza, oserei dire?
E por que a inimiga sabe
dessa fraqueza, imagino?
Откуда им известно об этом недостатке?
