Jason, meet Medea

 Meet Jason’s wife, Medea. Medea checks up on Jason and makes sure he can do his job. More technically, Jason is tied to the Atlantis by a long tether. So, all things being equal, as the ship moves and rolls, so should Jason pendulum style. This is bad! Medea is suspended above Jason and isolates this motion, preventing Jason from moving around too much. She also serves as an additional camera illumination platform to help keep tabs on what Jason is doing.
