Janus worked for the Lorien Defence Council and was assigned to pilot the ship containing the chosen Garde. When the Mogadorians attacked Lorien, Janus called his sister Zophie, shortly before departing, knowing that there was no way he was able to take her with him. He told her what he knew about the Elder's plan.
When the ship had reached a safe distance, Janus stayed in orbit for a week to wait for a sign of a resistance with a plan to return if there was a chance to aid and save the planet. This however was not to be and Janus tearfully reported that the ship's scans had picked up absolutely nothing from the surface.
Having arrived on Earth, Janus attempted to hide the Loric Ship and piloted it to the mountains in upstate New York but was spotted and a photograph was taken. A man named Eric Bird posted the photo which attracted the attention of the Mogadorians as well as Lexa, and the passengers of the second Loric ship. The Mogadorians soon caught up to him and tortured him for information which he eventually divulged.
Lexa and Zophie follow the lead of the photo which takes them to New York State where they speak to Eric and search the mountains for him. Lexa posts in Loric online and gets a reply from someone claiming to be Loric. She soon realizes that they are not and receives a video of a beaten Janus shortly before he is executed.
