“ | Piper, we are not going to turn this into a media circus. I’m sure he’s fine. He does take off occasionally. He always comes back. | ” |
–Jane talking to Piper McLean on the phone , in The Lost Hero. |
Jane is the former human secretary of Tristan McLean. Medea boasts that while she is very organized for a human, her mind is easily controlled. She is later replaced by the wind nymph, Mellie.

The Heroes of Olympus
The Lost Hero
Jane starts out as Tristan McLean's assistant. In one of Piper McLean's flashbacks, Jane reports Piper to her father for stealing a car and has her sent to another boarding school. She is later manipulated by Medea into telling Tristan that Piper was in danger, causing him to fly out to Mount Diablo where he was captured by Enceladus. Piper eventually called Jane from Camp Half-Blood to ask her where Tristan was, as she hadn't been able to get a hold of her father for a few days. Piper quickly caught on that Jane didn't know and hadn't even called the police. When Piper told her she needed to inform the authorities, Jane quickly claimed that Tristan disappears sometimes and would be fine before hanging up on Piper.
Later, while in Medea's department store, Piper learns that she was charmspeaking Jane in order to get to Tristan. Medea was the one who told Jane to tell Tristan that Piper was in danger, resulting in his capture. Jane was so much under Medea's influence that even when Medea insulted her, she happily agreed. After Piper manages to save her father and get him to a hospital, Jane was fired for not reporting that he was missing and subsequently replaced by the wind spirit Mellie.
The Trials of Apollo
The Burning Maze
It was revealed that Jane was working for Caligula of the Triumvirate Holdings. She, along with Tristan‘s accountant and film agent, were in on the emperor's plan to destroy everything Tristan built and cause him to go bankrupt.
Personality
Jane was originally seen as mean spirited but not villainous, as she was controlled by Medea, a sorceress, in The Lost Hero. Piper disliked her before she was controlled, implying that she was always a mean person. This is most likely due to the fact that Piper felt that her time with her dad was always interrupted by Jane coming to talk about business. She had an "organized mind" according to Medea.
She was later mentioned to be working for Caligula to destroy Tristan's wealth willingly and knowingly showing that she was even worse and had at least some knowledge of the emperor's.
Appearance
In The Lost Hero, it says she has hair "swirled tight into a bun."
