House of Anubis S01E58 - House of Sting

Joy is captured by her father, Victor, and the others in the Society of Ankh who order her to assemble the Cup as the Chosen Hour arrives. Meanwhile, a gloating Rufus tells Nina and Sibuna that not even Victor knows the full consequences of drinking from the Cup of Immortality. Joy fails in her attempts to assemble the cup, and she realizes that she isn't the Chosen One. Meanwhile Sibuna escapes Rufus and they make it back to the house. They find that Nina and Joy share the same birthday, but Joy says that her birthday was at 7PM while Nina was born at 7AM - the true seventh hour. They discover that Nina is the Chosen One and she reassembles the Cup, only to have it taken by Rufus, who returns. After Rufus drinks from it, he puts it in the fire and leaves. It turns out that Fabian switched the real elixir of life with a fake one and threw the real one away. Upon hearing this, Victor is devastated.
