Allison to Lillia EP8 - Princess and Hero

Nihito asks Fiona to show proof of her claim, and she produces a royal medallion which is confirmed to be real by one of the guards who was at the palace when it burned down years ago. Fiona goes on to accuse Nihito as having a part in her family's death due to a small cuff link of Nihito's that she had in her possession. Nihito retaliates by taking Fiona hostage and running up to the tower when Ker confronts him, and nearly loses his life. Allison and Wil fly their plane close to the tower which creates a strong wind that blows Nihito off the balcony which kills him. Later, Wil figures out that Fiona is not actually Francesca, and Fiona goes on to tell how she met Francesca the night of the fire, but only learned much later that she was her older twin sister.
