S01E47: Happiness Reflected on the Water's Surface

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.
