Subaru heads to Roswaal's mansion in hopes of finding out what's going on there and how he can fix it. He has Frederica and Petra evacuate to Arlam Village to protect them from Elsa's attack, then heads to Beatrice's forbidden library. He tries to get Beatrice out of the library, but her wishes don't align with his plans, and their discussion goes nowhere. Then, against all logic, Elsa finds her way into the forbidden library...
