Gosick - Season 1 Episode 17 The Box Lies in the Spiral Labyrinth

Victorique reveals to Kujo that her father brought her to the convent in order to bait out Cordelia and Brian. As the two escape, they become separated by an illusion. Victorique encounters Brian, who reveals that he is planning to stop her father and the Academy. Meanwhile, Kujo runs into Cordelia, who entrusts him with a ring and some words of encouragement for her daughter, then Marquis Albert de Blois himself. Albert attempts to force Kujo to surrender Victorique to him, but Kujo refuses and leaves. The floodgates shielding the convent are opened by a time-release trap set by Albert, flooding the entire area, and Kujo barely escapes with Victorique.
