The Familiar of Zero - Season 1 Episode 11 : Louise's Marriage 2012

With the arrival of Wardes and Louise alone, they meet up with Prince Wales in a seemingly deserted church. After finishing up business, Wardes suggests to Louise that they should just get married right then. Confused and repulsed by the idea, Louise tries to refuse his offer, but one of Wardes' allies comes out with a mind-control ring, forcing her into agreeing. With the Prince as the minister, the marriage proceeds and is nearly completed until Saito bursts into the church. Snapping Louise out of her trance, Saito rushes to rescue her. In response, Wardes kills Prince Wales, revealing that he is in fact involved with the rebels fighting the government Albion called Reconquista.
