From Tardis Wiki, the free Doctor Who reference
Leonidas was looking for Bernice Summerfield and took her to Ruth and gave her answers. He was a historian. He had lost his wife, as she believed she was a different person. When he went to the Layer of Poseidon he helped to find the truth. (AUDIO: The Temple of Questions)
He later tried to impress Benny by making Fish Finger sandwiches, and was told about the hierophants by Craisus. He accompanied Benny to a 27th century building that appeared in what she thought was ancient Greece. He grew attracted to Benny. He later was rewritten into a hierophant called Trellus.
