S3E21 Fountain of Youth

In Seville, Sydney and Nigel encounter a mysterious woman who requests a letter from the Duke, but she quickly vanishes. They soon discover that she was after Nigel's brother, Preston. He tricks them into visiting Lord Andrew's estate, claiming there’s a vial from the Fountain of Youth involved. Meanwhile, rival relic hunter Sean James is also on the scene, working for Lord Andrew, who is deeply in debt. After Sydney sets Sean off on a false lead, she, Nigel, and Bailey search for the vial. Lord Andrew captures them at gunpoint, but Mavis seizes the vial. Sydney confronts her, recovering it, only to find it empty. In a twist, Nigel allows his brother Preston to take the glory.
